Seamless integration: Removable panel with built-in cat door fits into horizontal sliding window tracks
Sturdy construction: Aluminum frame and weather-resistant flaps designed to withstand extreme conditions. You can also find the Endura Flap Cat Door for Windows in vinyl as well.
Energy efficiency: Low-E glass enhances insulation, prevents drafts, and allows natural light to enter
Please read instructions & notes thoroughly before installation.
Step 1Release Spring Mechanism
Loosen the height adjustment locks at the top of the pet panel with the screwdriver. This allows the spring mechanism to move freely up and down.
Step 2Check Panel Fit
To insert the panel into the top track, push up against the spring mechanism and swing the bottom of the panel up and over the threshold. Seat the panel on top of the small guide rail in the track.
You want to put the pet door in your track before applying any weather-stripping to ensure it fits.
If the panel fits well, proceed to the next step. See the FAQs if you have trouble.
Step 3Apply Weather-stripping
Once you’re sure the panel fits, remove it from the frame and lay it on its side on the ground.
Apply the foam weather-stripping by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides, trim to fit with scissors.
Step 4Install Center Post Weather Seal
The center post weather seal strip (draft stopper) should be installed on the inside of the home. It can be installed on either the back edge of the sliding window panel (Figure A) or the leading edge of the stationary panel (Figure B).
This strip prevents air from leaking between the sliding window and the stationary panel. Trim with scissors as needed.
Clean the edge of your window with rubbing alcohol before installing to assure a good seal.
Place the panel back into the window, then tighten the height adjustment locks to lock it in place. Installation complete!

FAQ
Will this keep out drafts?
This panel has low-e glass and the flap seals extremely well so it is great if you are looking for energy efficiency.
How do I measure my window to make sure that the panel fits?
You will need to open the window and measure:
from the deepest down inside the bottom of the track and all the way up into the track at the top
how wide the track is (must be at least 1” thick to accommodate panel)
How easy is it to install?
This cat door panel is very easy to install due to its spring-loaded design. Simply loosen the screws with a flathead screwdriver, pop the door into the track, and re-tighten them.
Is this door just for cats?
Small dogs can also use the flap, as long as they can comfortably make it through a 6"w by 11"h opening. Make sure to measure your pet before buying.
What do I do if none of these pet door sizes fit my window?
You can get a custom cat door if none of the pet door sizes fit your window.

Thank you for submitting a review!
Your input is very much appreciated. Share it with your friends so they can enjoy it too!
It was a great idea, and maybe if there is a flush perch on either side, the cats might use it. Right now, they are persistently ignoring it unless I push them part way through. It might help if the magnets were less strong.
The door is sturdy, and it keeps hot and cool separated even when there is wind. It is well made and fit well.
This didn’t seal properly and we had to tape it to prevent drafts. Also, the cat hasn’t been able to learn how to use it; we have to prop it open for him. So basically all we’re getting out if this $300 purchase is higher utility bills.
I would probably endorse it despite the drafts if the cat would just use it. You might have better luck. So, go for it, just buy tape, too.
Got our special order window within 3-4 weeks as stated on website & in excellent condition. We got it installed in our daughter's window with no problems or issues. The door is well made, quality materials & looks great too. It's the entrance to her newly completed catio. Very happy with your product - worth it to get a quality product that will last for many years. Cats are very happy too (:-))
