This glass panel has a pet door built into it. Because insertion of dog doors into glass panels is difficult all of the patio pet doors come preassembled with the pet door built in.

Choosing - Patio Pet Doors - Size

First choose the size your patio pet door needs to be. There are three different standard height ranges, yours should fit into one of them. Simply measure the distance from the base of the track (not the tip of a ridge) on the bottom to the base of the track on the top of your current door.
Patio Pet Door Short: 75” to 77 ½”
Patio Pet Door Regular: 78 3/4” to 81 1/4”
Patio Pet Door Large: 93 ¾ to 96 1/8

Choosing - Patio Pet Doors - Color

After choosing the height of your patio pet door choose the color of your patio pet door. Patio pet doors are made of aluminum and available in three different finishes to match your existing door;
Patio Pet Door in Aluminum finish.
Patio Pet Door in White finish.
Patio Pet Door in Bronze finish.

Choosing - Patio Pet Doors - Opening

Now it is time to choose the size of door that you need for your pet. For the height of the pet door, measure your pet from the top of the shoulder blades (withers) to the bottom of the chest (barrel). Then we suggest add an inch or two for easy passage. For the width, open your current patio door and by calling your pet thru the door determine the minimum width, then again add an inch. A slightly larger opening for your pet is not a problem, but an opening too small can be. You should find that the measurements will correspond to one of the below pet door sizes.

Patio pet doors come with a security lock. This is a simple yet effective pin lock that will lock your current sliding door to the patio pet door. For those who desire extra protection you can order your door with a KeyLock. Because there are different types of locking mechanisms on sliding doors, the KeyLock is generic. Your patio pet door will have a KeyLock installed on one side and will attach to a bracket mounted on your current sliding glass door. It is important to note that you cannot add the KeyLock at a later time, it must be done at the factory when you order your patio pet door. In addition you will need to specify if your current sliding glass opens to the right or left (the KeyLock needs to be installed on the correct side of the patio pet door).
