The Ideal "Fast Sash" Pet Doors for Sash Windows
series incorporates a spring-loaded adjustment at both ends which provides for a total adjustment range of 5".
These doors incorporate a flexible, safe flap that ranges from a Small to a very Large Super Large size.
Note that the plastic locking cover slides straight up. So it's important that the window not have an overhanging lip that would be in the way.
Also, unlike the Ideal Cat Sash or Hefty Cat Sash, the flap must be centered or the locking knobs would interfere with the locking covers.
In addition to choosing an adjustment range that encompasses the full width of your sash window track, the track itself must be at least 7/8" wide to accept the pet door framing.
Frame color is white only. Single pane glass. Good value in a sash window pet door.
These units are built to order. Allow 3-5 business days to fabricate.
