Installation Instructions

Complete Installation Instructions PDF File


Step 1: Remove the existing lock catch plate from your sliding door frame, as it will interfere with your new pet door.

Please Note: Your new pet door comes with two (top and bottom) mounting hangers attached. Please leave these hangers in place.

Step 2: Carefully remove the "H" Top Section from the top of the door. Place your pet door in position as shown. Make sure that the bottom hanger on the door is interlocked with the hanger on the frame.

Step 3: With the pet door in place, mark a pencil line to correspond with the top of the door on the edge of the frame. Remove the pet door panel. Measure down 5 ¼” and make a new pencil line, transferring the line down to the inside of the frame. This new line indicates the bottom edge of the "Top" Hanger. Place the top Hanger in frame and line up the bottom edge with the pencil line. Using the screws provided in Poly Bag #1, attach the hanger to the frame, keeping it centered on the frame.

Step 4: Place the two track fillers underneath the door. Re-hang the IDeal VIP pet door. The fit should now be snug to keep the pet door from moving in the track.

Step 5: Slide the "H" Section onto the top of the door over the springs. A gap of ¼” must be left at the sliding door-side area of the filler section to clear the door seal extrusion pieces.
Height adjustments to the "H" section may be made by cutting along the desired groove with a utility knife.

Please Note: Some doors may require adjustment to the "H" section. You may need to cut it to the required length with a hacksaw.

Step 6: After the "H" Top Section is in place, secure it in the door using two (3⁄16" x 5⁄8") screws provided in Poly Bag #2. Place the screws well away from the glass.

Please Note: This step is optional but will add structural stability and security.


How to Measure Your Sliding Glass Door for a Pet Door


Does the flap seal well?

The cat flap does have a magnet to help keep it sealed. However, if you want a dual-pane cat door with a flap that offered more wind resistance for extreme weather, the Endura Flap Vinyl Sliding Glass Dog Door would be the one to go with.
