Please read instructions & notes thoroughly before installation.
Step 1 Release Spring Mechanism
- Release the height adjustment locks by loosening the screws with a screwdriver.
Step 2 Test-Fit the Panel in Your Track
- Open the sliding door and insert the panel with the height adjustment locks 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. Tighten the height adjustment locks with a screwdriver.
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.
The dark area marks where you can trim:
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.

FAQ
|

Open, so they can go in and out as the please. In only, so that once they come in they can't go back out until you let them. Or out only, so once the exit they will need you to let them back in. |

|
My sliding door track has a triangular guide rail. Will this pet door still work? Some sliding glass door tracks have a triangle-shaped guide rail instead of a cylindrical pencil rail running along the middle. This pet door panel has an arch along the bottom that is designed to sit on top of a cylindrical pencil rail. Pencil rails are shorter in height than triangular guide rails, which means that the pet door panel would wobble on top of it rather than sitting flush with the rest of the track. To accommodate the pet door panel you will need to build up the sides of the triangular guide rail so that the tip is less than ¼” tall. Please reach out to customer service if you have any questions about this process. |
|
Will this panel work if my sliding glass door has a buried track? Some sliding glass doors have buried tracks. Since this panel has an arch along the bottom that is designed to sit on top of a pencil rail, it will not be secure in a slider with a buried track without modifications. We recommend securing the panel to the track wall with L brackets or toenailing it to the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss your options for a buried track. |

I have a hurricane patio door. Will this pet door work for me? Hurricane door track styles vary widely, so they are case-by-case. Please reach out to customer service to discuss your pet door options for your sliding door. |
|
Will this pet door work with Anderson and Pella sliding doors? Anderson and Pella sliding glass doors have an inner track wall but no outer track wall. Additionally, the pencil rail is on the outer edge of the track rather than in the middle. Since this pet door panel is designed to sit between two track walls and on top of a centered pencil rail, it cannot be installed in Anderson or Pella doors without modifications. We recommend building out your track and using L brackets or toenailing to secure the bottom of the panel to the inner track wall. Building out the track means adding a piece of wood or vinyl that is the same height as the pencil rail to the space next to the pencil rail. This creates a flat surface for the pet door panel to sit on. Next, you will need to secure the panel to the track wall. To do this, you can use L brackets or you can toenail the panel into the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss this process or different options for an Anderson or Pella sliding door. |
