Please read instructions & notes thoroughly before installation.
Step 1 Release 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 2 Check 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.
Step 3 Apply 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 4 Install 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).
- Place the panel back into the window, then tighten the height adjustment locks to lock it in place. Installation complete!

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 (:-))

United StatesBuy tape, too
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.

Shirley D. United StatesGood idea, but my cats have not taken to it.
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.
