Please read instructions & notes thoroughly before installation.
Step 1 Release Spring Mechanism
- Release the automatic height adjustment by turning the knobs located at the top of the panel counter-clockwise.
Step 2 Test-Fit the Panel in Your Track
- Open the sliding door and insert the panel with the knobs facing inside. Place the top edge into the top track of the window.
- Lift up and swing the lower portion of the panel into the bottom track.
- Slide the pet door panel against the door jamb. Make sure that the top is fully extended (not tilted to one side) and the bottom of the panel is on the ridge in the bottom track.
Step 3 Apply the Weather Stripping
- Once you are certain the panel fits, remove it from the sliding door track and lay it on a flat surface.
- Apply the foam weatherstripping 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 Reinstall the Panel
- Once the foam weatherstripping is installed, repeat steps 1-3 to install the panel. Hand-tighten the knobs by turning clockwise to lock the sliding glass pet door in place.
Whiskers & Windows Locking Details
Locking the Flap
- To change the 4-Way Lock setting, ensure that the flap is in the vertical resting position, and gently move the tabs left or right as desired. The tabs should move freely without requiring excessive force.
- Locked: Both tabs on the outside.
- Out-only: Both tabs to the right.
- In-only: Both tabs to the left.
- Unlocked: Both tabs in the center.
Installing the Clamp Lock (Sold Seperately)
- 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.
Alternative Locking Method
- 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.
FREQUENTLY ASKED QUESTIONS
What if my panel is slightly too tall?
You can trim up to 3/4” 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 or you will not be able to put the top back on.

What if my panel is slightly too short?
We offer height extensions that will add 3/4” to the top of the panel that you slide into the channel at the top. These are made from the same aluminum as the panel so you can match the color.
You can also make your own extension out of nominal 1” wood (which is 3/4” thick), such as a 1x3, if you need more than %" in height. Cut it to the same width as the panel and slide it into the channel at the top. Paint the wood to match your frame color. If the extension makes the panel feel unstable, you can secure it with screws.
