One-Piece Panel
Step 1 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 2 Insert Panel Into Track

- Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
Step 3 Apply Weatherstrip

- Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
- Apply the foam weatherstrip seal 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 and trim to fit with scissors as needed.
Step 4 Place Panel In Track

- Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.
Step 5 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.

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.

Variable Magnetic Resistance
Other Installation Options
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.
Troubleshooting Your Installation
What if my panel is slightly too tall?

You can trim up to 5/16" off the spring-loaded adjustment piece at the top. Remove the adjustment piece with a Philips-head screwdriver and use scissors or shears to cut down the flanges. Be careful not to cut too low.

What if hardware for the locking latch is preventing the door from sealing properly?
You may be able to remove the hardware, as it is sometimes secured with just a few screws.
If removal isn't possible, try installing the panel on the stationary side, as described here.
If neither option works, you can shim the panel to align it with the lock face. Depending on how far it protrudes, consider using thicker foam weatherstripping or a small wood spacer between the panel and the wall jamb.
My slider isn't closing evenly against the panel?
If your slider isn't level—a common issue in older homes—you may be able to adjust the wheels to realign it. Most doors have an adjustment screw near the bottom that allows you to raise or lower the wheels slightly.

If the slider is level but still misaligned, the issue could be with the metal height adjustment lock at the top of the panel. In some cases, you can use a rubber mallet to straighten out any slight curves.
If the height adjustment lock is hitting the edge, it may indicate that the bottom of the panel is seating deeper into the jamb than the top, creating a widening gap as you move downward. To correct this, use wood shims or weatherstripping in the jamb to push the bottom of the panel outward.
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 weatherstripping 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. You might also try semi-permanently installing the pet door.
The slider is on the outside track? How do I lock it?
If you're trying to lock the door, this can be an issue since a clamp lock, Charley bar, or dowel in the track may not work effectively. In this case, a foot lock is a good alternative, though it requires drilling into the front end of the stationary panel frame and a small hole in the sliding door frame.
Depending on your slider's handle design, you might be able to position a Charley bar between the handle and the edge of the stationary panel. This would allow the slider to press against the pet door, preventing it from being opened.
Alternatively, consider installing the pet door between the stationary glass and the wall for added security.
My pet is having difficulty with the large step-down going out or coming in.
In this case, you can use a ramp or small steps to reduce the height of the drop. Ensure that the distance between the top of the flap and the ground is enough for your pet to pass through comfortably without ducking or brushing against their back.
What if I have an alarm system?
The alarm company might be able to come out and move the sensor for you. So instead of one part being on the door and the other on the jamb, you would end up having one side on the panel that matched up with the one on the sliding door.
As there are many different types of alarm configurations we would recommend that you always consult the alarm security company first to discuss your options.
