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.
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 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.
For foam weatherstripping: Peel the backing off the foam weatherstripping. Press it along both edges of the panel, trimming as needed with scissors to ensure a snug fit.
For rubber weatherstripping: Clean the edge of your sliding door or window with rubbing alcohol to help the weatherstripping stick properly. Starting at the top or bottom, peel and press the strip into place with the folded edge facing indoors—align angled cuts if you have two pieces. For best results, apply the seal to the sliding door or window, but it can go on the pet door panel if needed.
Foam weatherstripping is applied onto both sides of the panel, but the rubber weather stripping only applies on the side of the slider door. Your panel will come with one type of weather stripping. You do not need both types.

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).
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!

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.
