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.
- 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.
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!
