PetSafe Sash Window Panel Tips
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, and depending on window design you may need to create a track with a quarter-round or 1" square wood strip.
- 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 additional insulation.
Removing Your PetSafe Sash Window Pet Door
- You will first need to loosen the width adjustment locks, you may first need to lift the pet door up to loosen the bottom screw.
- Then compress the window pet door and tighten the width adjustment locks once again for easy removal.
Removing the Press-Fit Closing Cover
- Step 1: Place thumbs in center of cover.
- Step 2: Place fingers on the back side of the wings sticking out of the sides of the cover.
- Step 3: Push with thumbs and Pull with fingers at the same time to unsnap the cover from the frame.
Lock Details
A great way to lock your sliding window is a Charley bar or screw in the track. Both work off the same concept - they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.
Switch the Side of the Flap
You can switch which side of the sash panel the pet door flap is on to best fit your home.
Step 1
- Remove the screws on the inside of the pet door frame and remove both frame pieces.
Step 2
- RRotate the flap assembly 180° so the opening is on the opposite side. Make sure the locking cover is on the same side as the width adjustment locks.
Step 3
- Reinstall the pet door using the original screws.

FAQ
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.
