Ideal Screen-Fit Cat Door
This cat door consists of a strong, clear ABS plastic flap embedded in a plastic frame.
What strikes us as interesting about this flap is that it isn't screen. The problem with screen is that we think a scratching cat trying to get in when it's locked is likely to tear screen. If this ABS plastic is strong enough, however, it might prevent that problem. We're looking forward to the first customer review to address this point.
Installation is easy; you only need a sharp knife or box cutter to cut the screen using the frame as a template. The cat door then snaps together. The instructions clearly state that it must not be installed lower than 3" above the bottom of the screen frame. This is because the door needs a bit of lag in the screen to serve as a sort of shock absorber. If the cat door is installed in the tighter part of the screen that is close to the frame, it will be easier for the cat to tear the screen while travelling through the cat door.
Support is from the screen only so it matters what kind of screen you've got. A genteel cat combined with strong, wire screen would be the best combination. Speaking of size, the box claims 9 3/4" x 10 1/2" flap dimension and suitable for cats to 20 lbs. We measure 8 3/4" x 10 1/4" but, either way, the opening is plenty big for even the biggest cat.
Ideal Screen-Fit Cat Door Installation Instructions
The Screen-Fit cat door is built to turn any screen into a cat door. It will fit any patio screen door, window screen or storm screen door. (not designed for retractable screen doors)
The door is a snap assembly, closed with a magnetic flap and dual slide locks to disable access to the door.
Step 1 - Select a screen for installation and remove the window or door screen from the frame
Step 2 - Lay the exterior side of the screen down on a flat, hard surface. Make sure the surface beneath the screen is protected from damage caused by a utility knife
Step 3 - Measure your pet from the floor to the top of their shoulder. The top of the frame should be installed 2’ above your pet's shoulders. It is also recommended you install the door at least 2” away from the frame to protect the door.
Step 4 - Put the outside of the frame, with the magnet facing the bottom of the door, under the screen. Make sure the arrows at the top of the frame are pointing up. Align the bottom and side edges with the outside of the frame. Use a sharp utility knife to cut horizontal slits in the screen at both top hinge groove locations. (Fig. 1)
Step 5 - Place the flap assembly in the outside frame with slide locks facing you. Do this by aligning both hinge posts at the top of the flap assembly with both hinge groove locations at the top of the frame. After, place the inside frame on top of the outside frame and align the cavities and posts (Fig. 2). Once aligned, you may use a mallet to carefully tap the frame together all around, sealing all gaps between the frames. This secures the flap assembly in place and hold the frames to the screen.
Step 6 - hold the flap up and cut the screen around the inner portion of the door with a sharp utility knife (Fig. 3). Trim away any excess screen from the inside preventing the flap assembly from swinging freely (Fig. 4).
Step 7 - Reinstall screen panel into window or door frame.
