Ideal Fast Fit Patio Pet Panel -- Super Large 15 x 20

Ideal Fast Fit Patio Pet Panel -- Super Large 15 x 20

Ideal Fast Fit Pet Patio Doors are perfect pet doors for single-pane sliding glass doors with aluminum frames. They have adjustable, spring-loaded top sections making them easy to install and remove in minutes. No assembly required. Fast 5-minute installation.

Super Large Flap Size: 15 x 20 pet door (w x h)

Overall Panel Width: 19 11/16" (use this measurement to determine if your sliding doors will open wide enough for human traffic after installation of the panel)

Minimum Track Width Required: 5/8"

Height of the Rise: The "rise" is the bottom part of the dog door that pets must step over to go through. This super large pet door comes standard with an 8" rise. If you have a small/short pet that will also be using this pet door you can order a lower 4" custom rise for an addtional charge. If your dog is very tall you can order a 12" custom rise so the dog will not have to stoop to go through the door.

Please measure your pet before making a purchase. The width of the pet flap must be greater than the width of your pet across the shoulders.

Please note: The Ideal Fast Fit Pet Patio Door will not work with double pane glass patio doors OR with vinyl sliders such as those made by Pella and Andersen. Please refer to Ideal VIP Vinyl Patio Panel Doors that are specifically designed to work with vinyl sliding doors.
