The best dog door for a security screen is the NAMSAN Dog Screen Door, with a 12 x 14 inch flap opening that suits most pets up to 80 lb and dual side locks that keep the opening shut. For a cat or a toy breed, the snap-in PetSafe Screen Door is the easier fit.
A dog door in security screen mesh needs one thing above all: a frame that holds the mesh steady around the opening. Security screens are stiffer than standard insect mesh, so a flimsy snap-in flap will sag or pull free.
The picks below all carry a solid frame and a flap that closes on its own.
Start with the NAMSAN if you have a medium or large dog. Move to the PetSafe or the PETLESO if your pet is small enough to slip through an 8 inch opening.
If your screen is heavy security wire, look at the Petway and its bracket system first. Our guide to how to install a dog door in a screen door walks through the cutting steps.

The best dog doors for security screens
Every pick here closes on its own and locks. The differences come down to flap size, frame depth and how the frame grips the mesh.
Match the opening to your dog first, then check the screen type.
NAMSAN Dog Screen Door: Best for most homes
- 12 x 14 in flap opening
- 14 x 16 in outer frame
- Dual side locks
- Magnetic self-closing flap
A large opening with dual side locks and a magnetic flap that closes after each pass. It fits most homes where a medium or large dog needs free access.
Pros
- Large 12 x 14 in opening
- Locks from both sides
- Thickened hinges and larger screws
- Replaceable flap
Cons
- Needs two people to install for the best fit
- Thick walls and solid doors need glue
The NAMSAN is the pick for most homes because its 12 x 14 inch opening handles everything from a cat to an 80 lb dog, and the frame is built to stay put. ABS plastic holds up to paws and daily use, and the screws and hinges are upgraded so the frame does not work loose.
Two blue side locks let you shut the flap from either side. That means your dog stays in at night while the screen keeps air moving.
The magnetic flap swings back and closes after each pass, which keeps insects out between trips.
Mounting matters with a big opening. Plan on two people so one holds the frame while the other drives screws.
The outer frame is 14 x 16 inches, so measure your clear screen area before you order. The flap carries a paw-shaped mesh insert, and both the flap and the screws can be replaced if they wear out, so the door stays in service instead of coming down.
Thick aluminum doors and solid walls need glue instead of screws. For a normal screen door or porch screen, the screw mount is enough.
This is the best all-round choice for a dog door in a security screen frame.
PetSafe Screen Door for Dogs & Cats: Best for small pets
- 8 x 9 1/4 in flap opening
- Snaps into the screen
- Sliding wind-locks
- Reinforced mesh
A snap-in door for cats and small dogs that installs without tools. The dual sliding locks hold the flap against breezes.
Pros
- Snaps in without cutting the screen
- Sliding wind-locks resist flapping
- Tear-resistant mesh
- Large door has fastening screws
Cons
- Small opening for pets up to 30 lb
- Small size locks shut and cannot be used by the pet
PetSafe makes the best pick for small pets. Its 8 x 9 1/4 inch flap suits cats and dogs up to 30 lb, and the whole door snaps into an existing screen without tools or cutting.
That snap fit is the reason to choose it. You press the frame into the screen and it holds, which makes it a fair option for a rental or a screen you might change later.
The high-impact plastic frame surrounds a mesh that resists tears and punctures. PetSafe lists the door for metal or vinyl coated fiber screens.
The large version adds fastening screws for a firmer hold. Sliding wind-locks keep the flap from flapping open in a breeze, but your dog can still push through.
The trade-off is size. A 30 lb limit rules out medium and large dogs, and on the small size the locks shut the flap so the pet cannot use it.
Choose this for a cat or a small dog in a standard screen door. If your screen is rigid security wire, a screw or bracket door holds better than a snap fit.
Ownpets Dog Screen Door 12"x14" Fits Large: Best for renters
- 12 x 14 in opening
- No-tool install in minutes
- Dual-side locking
- Mounts 6 to 9 in off the floor
A big opening that snaps onto the screen without drilling, so renters can remove it later. The mounting height guide helps small and large pets reach the flap.
Pros
- No drilling or permanent changes
- Fits metal, fiberglass and vinyl screens
- Dual-side locks
- Paw-shaped mesh insert
Cons
- Snap fit suits screens 0.25 to 0.5 in thick
- Hinges are lighter than the top pick's
Ownpets suits renters best. It snaps onto the screen with no drilling, so you can lift it off when you move out and leave the screen as it was.
The 12 x 14 inch opening matches the top pick and still fits pets up to 80 lb.
The frame is built for screens 0.25 to 0.5 inches thick and works with metal, fiberglass and vinyl-coated mesh. A template in the box lines up the frame so the cut is square.
Ownpets suggests mounting 6 to 9 inches off the floor, which puts the flap at a reachable height for both small and large pets.
The dual-side locks and the magnetic flap do the same job as the NAMSAN's. Where it gives ground is hinge strength: the frame is lighter, so a very heavy dog may stress it over time.
The snap fit also depends on the screen being in good tension, so a sagging screen needs tightening first.
Choose it when you cannot drill or when you want a door you can remove. Pick the NAMSAN instead if the dog is large and hard on the flap.
PETLESO Dog Door for Screen Door: Best for toy breeds
- 8 x 10 in flap opening
- 9.4 x 11.4 in outer frame
- Two sliding locks
- Magnetic auto-close
A compact door sized for Pomeranians, Yorkies and similar small breeds. Screws hold the frame firmly and the flap closes on its own.
Pros
- Sized for small breeds and cats
- Sliding locks at the flap bottom
- Screws fix the frame in place
- Paw design
Cons
- Too small for medium and large dogs
- Frame is 0.4 in thick
PETLESO is the best fit for toy breeds. The 8 x 10 inch flap is sized for Pomeranians, Yorkies, Maltese, Shih Tzus and similar small dogs, and it also works for cats.
The outer frame is 9.4 x 11.4 inches, so it takes less screen space than the large doors here. That matters on a narrow screen door or a small window screen.
Screws hold the frame firmly so it stays stable when a small pet pushes through. The frame is 0.4 inches deep, so it sits flat against most screen doors.
Two sliding locks at the flap bottom keep your pet inside when you are out. The built-in magnet closes the flap quickly after each pass.
A paw design on the flap adds a little decoration.
Skip it for anything bigger than a small dog, since the opening will not clear the shoulders. If your dog is medium-sized, the Enjoying or NAMSAN is the better fit.
Enjoying Dog Screen Door for Sliding Screen: Best for sliding screen doors
- 11.2 x 14.4 in flap opening
- 13.4 x 17.5 in outer frame
- Magnetic flap
- Lockable
A medium opening for sliding screen doors and thin metal doors. You trim the mesh into the inner flap yourself during install.
Pros
- Fits sliding screen doors and thin metal doors
- Locks for nights and rainy days
- Magnetic flap returns after each pass
Cons
- Needs a screwdriver and utility knife
- Inner flap arrives without a screen insert
Enjoying suits sliding screen doors and thin metal doors. The 11.2 x 14.4 inch flap fits dogs up to about 50 lb, and the frame measures 13.4 x 17.5 inches.
This one asks more of you at install. You need a flat-head screwdriver, a Phillips screwdriver and a utility knife, and you mount the trimmed mesh into the inner flap yourself.
In return, the frame screws down tight and the magnetic flap swings back after each pass. The frame is built for surfaces up to 0.67 inches thick.
The locks work for nights and rainy days, or any time you want your dog to stay in. The opening sits between the small and large doors here, so it fits a mid-size dog that would be cramped in an 8 inch flap.
The extra trimming step is the trade-off against snap-in doors. Choose it if your sliding screen door needs a stable, lockable flap and your dog is around 50 lb or under.

Petway Dog Door for Screen Doors: Best for security mesh
- L-Bracket Adapter System
- Lockable flap
- Slim profile
- UV-resistant ABS
An Australian-made door with brackets made for security screens and insect mesh. The slim body lets a sliding door still run past it.
Pros
- Brackets suit security screens
- Slim design keeps sliding doors moving
- Lockable flap
- UV-resistant build
Cons
- Small size only
- Three sizes exist, so match yours carefully
Petway is the best pick for heavy security mesh. Its L-bracket adapter system grips security screens and insect mesh, which is the job most snap-in doors struggle with.
The slim body means a sliding door can still run past the frame without catching. That is the reason to choose it on a sliding security screen.
The flap locks for security and control, and Petway says the ABS build resists UV damage, so sun exposure matters less on a south-facing porch.
It is Australian-made and comes in three sizes. This small size suits a small dog or a cat.
Petway lists it for security screens and insect mesh enclosures, so it covers a porch screen as well as a patio door screen. If you need a bigger opening, look at the large doors here rather than forcing a small frame.
The trade-off is choice: you have to order the right size from the range. Pick it when the screen is rigid security wire and you want brackets made for that surface.
The instruction video on Petway's site helps if the bracket fit feels unclear.
ikuso Dog Door for Screen Door: Best for quiet closing
- 10.2 x 14.3 in opening
- Sealing brush around flap
- Dual side locks
- Magnetic catch
A white door with a sealing brush that softens the flap's close. The medium opening suits dogs up to about 60 lb.
Pros
- Sealing brush quiets the close
- Locks on both sides
- Puncture-resistant mesh
- White frame
Cons
- Medium opening only
- Two people make alignment easier
The ikuso door is best for quiet closing. A sealing brush around the flap softens the close, so it does not thump when your dog runs through, and the strong magnetic catch still seals against insects.
The opening measures 10.2 x 14.3 inches and suits medium to large dogs up to about 60 lb. Mount it so the top of the flap sits near your dog's shoulder height.
The frame is high-impact ABS with puncture-resistant mesh, so it stands up to scratching and daily use.
Two side locks restrict access when you need it. The white frame blends with a light-colored screen door.
Install takes a screwdriver and a utility knife, and two people make alignment easier. The 1.5 lb frame is light enough to handle alone once the holes are marked.
Where it loses to the top pick is the opening size, since 60 lb is a step below the NAMSAN's 80 lb. Choose it when a quiet flap matters more than maximum size.
Billionchains Dog Door for Screen Door: Best for screen porches
- 12 x 14 in inner size
- 14 x 16 in outer frame
- Magnetic closure
- Two slide-key locks
A porch and garden door with a big opening and locks that work from either side. The magnets pull the flap shut without blocking a push-through.
Pros
- Locks from inside or outside
- Magnet strength suits pets pushing through
- Fits balcony, porch and window screens
- Inner flap keeps bugs out
Cons
- Needs two people to install cleanly
- Fitting height decides how well it works
Billionchains is best for screen porches. The 12 x 14 inch opening fits medium to large dogs, and the two slide-key locks work from inside or outside the screen.
The magnets along the flap's bottom corners pull the door closed without being too strong for a pet to push through. That balance is what makes a flap usable day after day.
The inner flap carries a screen insert, which adds a layer against bugs. The outer frame is 14 x 16 inches, so it needs a clear panel of similar size.
You can fit it into a balcony, garden, porch or window screen. Mounting height decides how well it works: set the flap opening an inch or two above your dog's shoulders.
Two people make the install cleaner, since one holds the frame while the other cuts and screws.
The trade-off against the top pick is that the opening height must be measured carefully, because the frame is fixed once screwed down. Choose it for a porch screen where you want locks on both sides.
Kagoty Large Dog Door for Screen Door: Best for large dogs
- 14 x 12 in door access
- 16 x 14 in frame
- Two blue locks
- Magnetic flap
A large frame for big dogs and large cats. The two locks shut the opening completely and the flap closes fast after a pet passes.
Pros
- Large opening for big dogs
- Locks fully with two blue locks
- Magnet closes the flap quickly
- About 10 minutes to install
Cons
- Big frame needs more screen space
- Treats and toys help train the first uses
Kagoty is the best pick for large dogs. Its 14 x 12 inch door access is the widest opening in this group, set in a 16 x 14 inch frame, and it suits medium to large dogs and large cats.
The two blue locks shut the opening completely for security. The internal magnets close the flap fast after a pet passes, which keeps small insects from following the dog inside.
Kagoty says the install takes about 10 minutes: screw the frame in place, cut the screen, then insert the flap. The steps match the order the other screw-mount doors use.
Because the frame is large, it needs more clear screen space than a small door. Measure the screen panel before ordering so the frame does not overlap the door's edge rail.
Treats and toys help a dog learn the flap in the first few days, and Kagoty suggests them for pets that hang back at first.
Choose it when your dog is big and the screen panel is wide enough. For a medium dog on a tighter screen, the Billionchains or NAMSAN fits better.
CEESC Dog Screen Door: Best for two-way control
- 12.2 x 14.56 in inner size
- 14.56 x 16.92 in outer frame
- Two switch modes
- Magnetic flap
Switch tabs set the flap to in-and-out or fully locked. The large white frame fits small, medium and large dogs.
Pros
- Switch tabs for in-and-out or locked
- Fits dogs and cats by waist size
- Magnetic auto-close
- White frame
Cons
- Frame is 0.7 in thick, so check your screen depth
- Large frame needs clear screen space
CEESC is best when you want two-way control. The switch tabs on the flap set it to in-and-out or fully locked, so you decide when your dog can pass.
The inner size is 12.2 x 14.56 inches and the outer frame is 14.56 x 16.92 inches. CEESC sizes it for small, medium and large dogs and cats with a waist under 38.3 inches.
That waist figure is a different way to size a door, so measure around the widest part of the body as well as shoulder height. The built-in magnet closes the flap when your pet leaves.
A white frame and a strong mesh build make it a good look for a light-colored screen. Install is a four-step job with instructions included: press the two frame halves together, tighten the nuts, trim the screen to the inner edge and snap the top of the door into place.
The trade-off is depth. The frame is 0.7 inches thick, so check that your screen door can take it.
Choose it when you want switch control over when the flap opens.

How we compared these dog doors
We started with what a dog door in security screen mesh needs: a frame that holds rigid wire steady and a flap that seals after each pass. Each pick here has a solid frame and a magnetic or mechanical close.
Then we checked flap size against the maker's weight range. A door rated to 80 lb needs a bigger opening than one rated to 30 lb, and the two figures should agree.
We noted frame thickness because it decides whether a screen door can take the door without binding.
Lock type came next. Side locks and slide keys keep a dog in at night, while switch tabs give two-way control.
We also weighed install effort: snap-in doors suit renters, while screw-and-cut doors hold firmer on a rigid security screen.
Our score weighs specs, features and buyer feedback against what you're shopping for. Doors with a bigger opening, solid locks and a simpler install score highest.
The best pet door guide covers options for cats and dogs in walls and solid doors.
What size dog door fits your dog and screen?
Measure your dog's shoulder height first, then add an inch or two. A door rated to 80 lb like the NAMSAN or Ownpets gives a large dog room to pass without crouching.
A toy breed can use an 8 inch opening like the PetSafe or PETLESO.
Then measure the screen panel. The frame must sit inside the clear mesh area, away from the door's edge rail.
The Kagoty's 16 x 14 inch frame needs more room than the PETLESO's 9.4 x 11.4 inch frame. The CEESC takes up the most room at 14.56 x 16.92 inches, so a narrow panel may not fit it.
Mounting height follows the dog, not the frame. Set the flap opening about an inch or two above shoulder height so your pet walks through without ducking.
Ownpets suggests 6 to 9 inches off the floor.
Small dogs and cats
An 8 x 9 1/4 inch opening suits pets up to 30 lb. Pick the PetSafe for a snap-in fit or the PETLESO for screws and a lower frame depth.
The PETLESO's 0.4 inch frame sits flatter than the CEESC's 0.7 inch frame. Our dog door for small dogs guide goes deeper on toy breeds.
Medium and large dogs
Aim for a 12 x 14 inch opening or larger. The NAMSAN, Ownpets and Billionchains all fit that size, and the Kagoty goes one step wider at 14 x 12 inches.
Check the weight rating against your dog's size before you buy. A dog near the top of a rating will use the opening more heavily, so the hinge and screw quality matters more.
Which mount suits your security screen?
A snap-in door suits a standard screen and a renter. A screw-mounted frame suits a security screen that sees daily use.
Brackets suit rigid wire mesh best.
If the screen is normal insect mesh or fiberglass, a snap-in door like the PetSafe holds well and needs no tools. If the screen is rigid security wire, choose a screw frame or a bracket system.
The Petway's L-bracket adapters are made for security screens and insect mesh.
Screw-mount doors such as the NAMSAN and Ownpets hold tighter on a porch or patio screen. Plan for two people and a screwdriver.
For sliding screen doors, keep the frame slim so the door still runs past it; the Petway's slim body is designed for that.
Snap-in, screw-in or bracket
Snap-in doors press into the screen with no cutting. Screw-in doors use fastening screws through the frame and need a cut in the mesh.
Bracket doors grip from the sides and suit heavier wire. Match the mount to how much load the screen carries and whether you can undo the job later.
Do locks and magnetic flaps matter?
Yes. A lock keeps your dog in when you want, and a magnet closes the flap so insects stay out.
Pick a door with both if your dog goes out at all hours.
Side locks on the NAMSAN, PETLESO and Ownpets let you shut the opening from either side. The CEESC goes further with switch tabs for in-and-out or locked.
The PetSafe uses sliding wind-locks that resist a breeze without blocking your dog.
A magnetic flap closes on its own after each pass. That matters on a security screen, because a flap left open lets bugs in and weakens the frame's hold over time.
The ikuso adds a sealing brush so the close is quiet. The PetSafe's small size locks shut and cannot be used by the pet, which is worth knowing if you plan to lock it often.
How hard is the install on a security screen?
Cutting a security screen takes more care than cutting insect mesh. Screw the frame down first, then cut the mesh to the inner edge so the opening stays square.
Two people make the job easier.
Most doors here follow the same order: mount the frame, cut the screen inside the frame line, then fit the flap. The CEESC spells out the steps in its instructions.
The Enjoying asks you to mount trimmed mesh into the inner flap yourself.
Rigid security wire needs a sharper cut and a steady hand. Use a utility knife with a new blade and cut along the frame edge.
Our how to install a dog door in a screen door guide covers the cutting and fastening steps in order.
Do dog doors in security screens keep bugs out?
They do when the flap closes fully. A magnetic catch pulls the flap shut after each pass, and a screen insert in the inner flap adds a second layer.
A flap left propped open defeats both.
The NAMSAN, Billionchains and CEESC all carry a mesh or screen insert in the flap. That insert is the barrier that keeps insects from following your dog through.
The magnetic close then seats the flap against the frame. The ikuso's sealing brush adds a soft edge around the flap, which helps the close seat evenly.
Check the flap after a week of use. If it hangs slightly open, adjust the frame or tighten the screws so the magnet can pull it home.
That small step is what keeps a dog door in security screen setups working as a bug barrier. A door with a light hinge is easier to keep seated than a heavy one that sags.
Which dog door should you buy?
Buy the NAMSAN Dog Screen Door for most homes. Its 12 x 14 inch opening covers most pets up to 80 lb, the dual locks shut it when you need, and the upgraded screws and hinges hold the frame steady on a security screen.
Pick the PetSafe if you have a cat or a small dog and want a snap-in fit with no cutting. The Ownpets is the renter's choice when you cannot drill.
For rigid security wire, go with the Petway and its bracket system. For a big dog on a wide screen panel, the Kagoty's 14 x 12 inch opening is the roomiest.
The ikuso is the pick when a quiet close matters, and the CEESC when you want switch control over the flap.
Measure your dog and your screen before you order. That single step decides whether a door fits and works as a dog door in security screen mesh should.

Frequently asked questions
Will a dog door in a security screen weaken the mesh?
A small cut-out does not change how the screen works as a barrier. The frame spreads the load around the opening and the mesh stays tensioned on all sides.
How do I stop my dog using the door at night?
Use the locks. Most doors here have two side locks or sliding tabs that hold the flap shut, so your dog stays inside while the screen still lets air through.
What size dog door do I need?
Measure your dog's shoulder height and add an inch or two. The flap opening should sit just above the shoulders when the frame is mounted at the recommended height.
