Step 1 Adjust the Top Piece

how to adjust top piece
  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.
  • Watch out, it might jump at you the first time!

Step 2 Test-Fit the Panel

fit panel into track
  • Insert the panel into the top track of your framing, push the panel into the spring mechanism and swing the bottom of the panel up and over the threshold into the rail at the bottom.
  • If you can't quite clear the track, try swinging in from the outside as the outside track wall may be shorter.
  • If the panel still doesn’t fit, see the FAQ for guidance.
  • Do not apply the weather stripping before test fitting the panel

Step 3 Apply the Weather Stripping

  • Once you have confirmed the panel fits, remove the panel from the track and lay it on its side.
  • 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. Use scissors to trim the strip to fit the length of your panel.
  • Flip your panel around to apply on the other side.

Step 4 Install the Panel

Locking Your Window

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 track clamp

This clamp has a thumb screw which tightens by hand to prevent the sliding window pane from moving beyond the clamp’s placement. For windows manufactured with the slider on the inside track, the lock can usually be installed on the raised track.

If you aren't able to use the lock that comes with the panel:

A great alternative to locking your window 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 pane away from the pet door panel.

Frequently Asked Questions

What if my panel is slightly too tall?

You can trim up to 5/16” off the spring-loaded adjustment piece at the top. This can be done by removing the adjustment pieces with a #2 Phillips Head screwdriver and cutting down the flanges. Be careful not to cut too low.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1-1/2" you can use small wooden shims or extra weather-stripping to fill in the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel.
