Tips for Choosing the Right Size Sash Pet Door for your Window:
- Raise the window and measure the full width including into the track on both sides. Be sure that the pet door you choose has the proper adjustment range for your window.
- Second, be sure the window can be raised high enough to accept the pet door.
- Finally, some models include a locking cover that needs to slide down a track over the flap. If you're purchasing one of these, be sure you've got enough clearance above the pet door for the locking cover to slide straight up. There must be no overhang or 'lip' in the way.
