Adjusting the Pet Door for your Window 

Due to the fact that there are many types of windows, you may need to modify your installation using shims or similar materials. If there is a gap, you can use the shims to even out the pet door. A foam weather stripping can also be used around the edges for add insulation.

How to Measure Your Sash Window for a Pet Door


What do I need to know/measure before I order?

First raise up your window and check that it can go up far enough to be left with an opening 15" high. Next measure the width of the track from left to right, including going inside the track on both sides. Last measure how wide the track is that the window slides in (needs to be at least 1")

How wide does the track have to be for the PetSafe Sash to fit?

Track width needs to be at least 1" thick.

Can I choose what side the door is on?

It comes standard on the left, if you are looking from the inside of the house. You can switch it by taking out the pet door (needs a screwdriver) and flipping it upside-down.

Is this easy to install?

This is designed to be a fairly simple install that does not require any tools. Take a look at the video under the installation tab to see if it something you would be able to do.

Will this door be good for more extreme weather?

The pet door has flexible flap with a magnet on the bottom to help hold is shut. The glass is single pane for moderate insulation value, that said this is recommended for more mild climates or if you a simply on a fixed budget. You can also check out our full list of recommended extreme weather dog doors.

My cat is having a hard time opening the flap is there something I can do that would make it easier?

You can by removing the flap, although you would have a big open hole. Some electronic window cat doors open automatically for your cat, or at least have a light weight flap that is easy enough for them to push. Make sure you also check out our guide on training your cat how to use a cat flap.

What if I mismeasured?

If you've mismeasured, you may be able to fix it. To make your sash cat door about 3/4" wider, you may purchase a width extension (or make your own using 1" x lumber). To make your window kitty door insert slightly shorter you may trim the side flanges on the spring loaded adjustment piece with a hacksaw or a jigsaw with a metal cutting blade.
