These measurements are a guide only, make sure the pet door is installed so that the opening is at least 2? above the pet’s back. There is only one size for electronic doors, you will need to estimate based on pet size.

Full Measurements

The frame measurement lets you know how large of a space will be used by the dog door, the pet space start lets you know where the top of the pet space is in relation to the top of the frame, the pet space tells you how much room your pet will have to fit through the door, and the cut hole measurement tells you how much material you need to cut out of your door or wall.
