Track Height Adjustment Range is the measurement of your window height from the lowest point of your track to the highest point. Review our Track Measuring Guide for more information. The Endura Flap Cat Door for Horizontal Sliding Windows comes in two adjustable ranges:
34"– 37"
46"– 49"
If your measured track height does not fall within one of the ranges above, we can make a custom height. Choose the range that your track height falls into and when ordered you will be asked to give the exact height of your slider track inside very top to very bottom. In each case you will have 3" of height adjustment with the height you specify approximately in the middle of that range. Custom height option may take up to 4 weeks to special order the glass and build the panel. The ranges are:
Between 23"– 34"
Between 37"– 46"
Over 49"
CAUTION: If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

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 a 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!
LOCK DETAILS
Since you likely can no longer use your window’s original lock, we have provided you with an alternative locking method to keep your home secure.
Installing the window clamp: This clamp has a screw that tightens by hand to prevent the sliding door from moving beyond the clamp’s placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door’s raised track.
If you aren’t able to use the lock that comes with the panel: A great alternative to locking your sliding glass door is a Charley bar or dowel in the track. Both work off the same concept - they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.

How to Adjust the Magnet Strength on an Endura Flap
FAQ
How easy is this to install?The spring loaded design makes installation of the cat door panel very easy. Once it is in place you can't remove it from the outside either, so it's safe and secure. |
How do I measure to make sure that it 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. You will also need to measure how wide the track is, since the panel is 1" thick your track has to have at least that width to be able to accommodate it. |
How strong is the seal on the pet door flap?The magnets are stronger than your typical off the shelf pet door, so they will have to push the flap a bit harder to get it open. You can adjust the magnets in the beginning for training purposes by reducing their strengths, however you will lose some of the sealing power. |
Is this 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. |
Does this keep out drafts?The flap seals extremely well so it is great if you are looking for energy efficiency. |
