Ideal Lockable Cat Flap Side Sliding Window Inserts

Custom Made Pet Door Window units

Flexible Flap Inserts for Side Sliding Windows

The Ideal Lockable Cat Flap Side Sliding Window Insert is just like a patio insert for sliding glass doors; but made shorter for vertical windows. The top of the unit is spring loaded to give you a 2.5" adjustment range for easy fitting and removal. A locking pin is included that you may install on the frame of your sliding window. Most customers use a small stick behind the window in the track instead as they do not wish to install any hardware. All weather stripping is included as well as a bug protector (draftstopper) that is installed to cove the gap created when the window insert is installed.

Pet Opening - 6 1/4"w x 6 1/4"h
4-Way Locking Control

Note: If your measurement is within a 1/2" of the bottom of an adjustment range (in chart below), then you will want to call us to place your order so we can make an alteration to the unit for proper fitting.

You may want to consider a pet ramp or stairs for your window insert if the height from the floor surface seems a bit dangerous for your pet. These ramps are an excellent solution to those types of problems and come in a wide variety of shapes, colors, and sizes. For a complete selection of quality, furniture grade ramps please see our
Pet Ramps and Steps.

[photo] Ideal Side Sliding Window Insert top Section
The top spring-loaded adjusting section of the Side Sliding Window pet door appears as an "H" piece when viewed from the side. The overall width of this piece is 13/16" (Will fit into most any sliding window track).

The spring-loaded adjustment provides for a 2 1/2" range for proper fitting into your opening. Most top tracks in sliding windows do not have any center rails, however, if you do have this feature then the top section can straddle any rail at the top 5/8" wide or narrower.

The spring-loaded top is secured with 2 thumbscrew locks, accessible from inside the house only, someone from the exterior of the house would not be able to compress or remove the unit.

The bottom section of the Side Sliding Window Pet Door has an overall width of 5/8". A semi-circle, "C" channel is centered and runs the length of the bottom. This "C" channel is design to straddle the center rail in the channel on the bottom of the sliding window track.

By straddling this center rail, the Side Sliding Window Pet Door will remain centered to the frame of your sliding window when closed to this unit.

Note:If the center rail in the channel on the bottom is wider than 5/16", then this patio Insert will not be able to straddle it and as a result may not fit properly in your opening.

Double Check overall channel widths also to ensure proper fitting - must be at least 13/16" at the top and at least 5/8" wide in bottom and side channels.
