This weather tight, dual pane, dual flap Hale pet door fits in a vertical sliding sash style window (aka sash window, double hung window).
This unit has an end which telescopes about 1.5 inches to fit into the track just like a window fan or air conditioner. Minimum track thickness must be at least 1" to accomodate the thick framing on this pet door. The picture shows the pet door with the locking cover halfway slid in. If you are looking for a window mount pet door, they don't get any better than the Hale Security door. The pictures of the frame colors will vary with your particular monitor and the brown background on the pictures doesn't do us any favors, but they are shown to give an approximate idea of the colors available. Satin is actually a brushed aluminum, similar to the bottom of a soda can. A good description of the beige is like coffee with 2 creams in it. White is bright white, bronze is almost black. This is a custom made pet door, so it is non- refundable. It takes 2-3 weeks for delivery from the order date.
We require three measurements from your window to complete the order.
Measurement A is the maximum opening height of the window.
Measurement B is the tricky one. If you think of the tracks as two U shapes that face each other, then we want the measurement from the bottom of the U on one side to the tip of the U on the other side.
Measurement C is the thickness of the track. The track must be at least 1" thick to accomodate the heavy duty framing on this pet door. We also need to know which side to mount the flaps on.
The side is determined from the inside looking out. Simply choose left or right.
