The PetSafe Classic Pet Door features PetSafe's Ultraseal all-weather, energy conserving insulating dog door flap to reduce heat loss. The soft, transparent dog door flap is easy to open, yet is durable for large dog breed use. This insulating dog door also comes with PetSafe's Grip-Trak insulating, locking security cover for times when you want to block access to the dog door.
The dog door's telescoping, adjustable frame creates its own protective inner frame in doors ranging from 1/16" to 2" in thickness. The PetSafe Classic Pet Door can also be installed within walls, however, additional customer framing is required.
How to measure your pet:
Step 1: Dog Height
Measure your pet from the top of the shoulders to the bottom of the chest, just behind their front legs. Add an inch or two for comfort.
Step 2: Dog Width
Measure the widest part of your pet (chest or hips). Add an inch or two for comfort.
Note: Allow room for pet's growth if they are not fully grown.
