Please read instructions & notes thoroughly before installation.
One-Piece Panel
Step 1 Adjust the Step Over (Optional)
- The top of the flap should be positioned to be at least 1” above the top of the pet’s shoulder.
- If the factory setting is not suitable, please adjust it before proceeding. If the current setting is suitable, proceed to the “Installation Instructions” section.
Step 2 Adjust the Screws
- Lay the entire panel on a flat surface.
- Using a #2 flat head screwdriver, remove the bottom side-screws and loosen the upper side-screws. Screws were tightly installed to hold the panel together during shipping; a power tool* is recommended.
Step 3 Adjust the Spacers
- Once the bottom screws have been removed and the upper side-screws loosened, the Pet Door Assembly and spacers can be removed by sliding the sections down and out of the panel.
Step 4 Replace the Spacers
- Replace the spacers and the Pet Door Assembly by sliding them back in a different order to achieve the desired height. You can move the spacer below and above the flap to raise or lower the flap height.
Step 5 Tighten the Screws
- When finished, replace the bottom side-screws and tighten the next upper-side screws.
Step 6 Unlock 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 7 Test Fit the Panel in Your Track
- 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 8 Apply the Weatherstripping
- Once you’re sure the panel fits, remove it from the frame and lay it on its side on the ground.
- 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. Install on both sides, trim it fit with scissors.
Step 9 Install the Draft Stopper
- The center post weather seal strip (draft stopper) should be installed on the inside of the home.
- Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
- Repeat step two to install the panel in your track.

Step 1 Adjust Step Over Height (Optional)
- The top of the flap should be positioned to be at least 1” above the top of the pet’s shoulder.
- If the factory setting is not suitable, please adjust it before proceeding. If the current setting is suitable, proceed to the “Installation Instructions” section.
Step 2 Rearrange the Pieces (Optional)
- Simply slide the pieces up and out from the bottom half of your panel to rearrange.
- Loosen a bottom screw if the pieces are too snug to move.
Step 3 Reconnect the Pieces (Optional)
- Replace the spacers and the Pet Door Assembly by sliding them back in a different order to achieve the desired height.
- You can move the spacer below or above the flap to raise or lower the flap height.
Step 4 Screw the Pieces Together

Step 5 Align the Connectors
- Remove the 2 flat head sectional connector screws from the exposed part of the connector on each side.
- Align the aluminum connectors extending from the bottom flap panel section with the top glass panel section.
- Press the aluminum connectors into the holes at the bottom of the top glass panel section.
- Ensure locking cover & height adjustment locks are on the same side!
Step 6 Tap the Pieces Together
- Gently tap the bottom surface of the panel against the ground to completely insert the connectors.
- Protect hard surfaces to prevent scratching.
- The components of the panel are designed to slide together very tightly.
Step 7 Secure the Sections
- Fasten the two panels together using the four flathead screws.
- Use the included flathead screwdriver to tighten all four flathead screws so the two halves of the door are pulled together.
Step 8 Adjust Spring Mechanism
- Loosen the height adjustment locks at the top of the pet panel. This allows the spring mechanism to move freely up and down.
Step 9 Test Fit the Panel in Your Track
- 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.

Lock Details
Since you cannot lock your sliding door to your panel pet door, we have provided you with alternative locking methods to secure your home:
Installing the sliding door 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.
Other Installation Options
Semi-Permanent Installation:
You might choose to secure the panel in your track with screws. This can be done by drilling screws at an angle in the top and bottom tracks. We recommend doing this from the outside to minimize damage to the sliding glass door frame. One-way screws will prevent tampering or removal of the panel from the outside.
Stationary Panel:
Some stationary sliding door panels can be unfastened and moved over to one side so that you can install the pet door panel between the jamb and stationary panel.
Avoid damaging your sliding glass door by checking that your door can move and that you can reinstall it properly before trying to uninstall the unit.
You will still lose space in your slider to move through, however, you will be able to use your existing sliding door lock to secure your home. Installing your pet door this way is also great in that you already have an alarm system in place.
If your sliding glass door slides on the outside track, using an alternative lock might not be possible, so this allows you to still lock your door.
NOTE: You can do the stationary panel install with the regular spring actuator method – no need to screw it in.
FAQ

I am looking at the multi dog sized doors for a sliding patio door. What are the differences between a vinyl dog door and an aluminum? The primary differences between vinyl and aluminum dog doors for sliding patio doors-- besides the material they are made out of--are in their thickness, energy efficiency, and material compatibility. Vinyl doors are typically 1.5" thick, offer better insulation, and match well with vinyl sliding doors due to their energy-efficient nature and thicker frames. Aluminum doors, on the other hand, are 1" thick, less insulating but highly durable, and they pair well with aluminum sliding doors for a consistent look and maintenance ease. When choosing between them, we recommend getting the panel that matches your sliding glass door's track material (aluminum with aluminum, or vinyl with vinyl) and will fit into your track's width. |
