How It Works

The screen door flap installs directly into an existing screen window — you cut an opening in the screen mesh to the size of the inner door, then clamp the flap frame around the mesh using the included pin buckles. The roller-type flap swings open in both directions when a pet pushes through, then returns to the closed position to maintain the insect barrier. The lockable mechanism allows you to restrict access when needed. Note: the product is a door frame only and does not include a screen mesh — it is designed to be installed into an existing screen window.

Frequently Asked Questions

Q: Does this come with a screen mesh?
A: No — the product is a door frame only. It is designed to be installed into an existing screen window by cutting an opening in the mesh and clamping the frame around it. The screen mesh itself is not included.

Q: How do I install the screen door flap?
A: Lay the flap flat and separate the two frame pieces. Clamp the frame around your existing screen mesh using the pin buckles, then cut along the inner door edge to create the opening. Insert the hook accessories at the bottom to control the locking function.

Q: Which size should I choose?
A: Choose based on your pet's shoulder height and width. The S size (inner opening 25 × 19.7cm) suits small to medium cats and dogs; the L size (inner opening 40 × 30cm) suits medium to large dogs.

Q: Can this be used on any screen window?
A: The flap is designed for standard screen windows with a flexible mesh. Very stiff or rigid mesh may create too much resistance for the flap to operate smoothly — a softer, standard screen mesh is recommended.

Q: Is the flap mosquito-proof when closed?
A: Yes — when the flap is in the closed position, it maintains the insect barrier of the screen window. The roller mechanism returns the flap to the closed position after each use.
