You can estimate the panel width by adding 4" to your desired flap width.

1 Step Over is the height of the flap above the base of the pet door. We suggest that flap height + 'step over' should about equal pet shoulder height. 

These dimensions are approximate within 1/2".

2 The overall width is equal to flap width plus 4".

Installation Instructions


  • Tape measure

  • Hacksaw

  • Electric drill

  • 1⁄64” drill bit (included)

  • #2 Phillips head screwdriver

  • #6 metal screws (included)



Step 1: Clean the glass on the patio door and panel.

Step 2: Measure the door frame height inside the track from the very bottom to the very top.

Step 3: Mark the side rails of your panel insert and cut them to length with the hacksaw. Make sure to leave clearance so that the panel can clear the rail wall and fit into the track.

Step 4: Place the panel into the track and make sure it fits.

If you’re installing on the stationary side, close the stationary panel up against the pet door and check for air gaps. If installing on the sliding glass door side, close the slider up against the pet door panel and check for air gaps. Any air gaps between the edge of the sliding glass door and the pet panel will be covered when the lock strip is installed.

If necessary, apply foam weather stripping (available at hardware store) to the side rail of your pet door panel.

Step 5: The panel insert should be held tightly against the door jamb lip to allow you to drill holes and screw the pet panel in place. If there is not enough of a lip to drill through, the pet panel can be fastened in place with silicone caulk.

The side rails of your pet panel are notched at the bottom so that it can straddle the wheel track in the door jamb, but it does not have to do so. You may need to set the panel on top of the wheel track in order to pull it tight enough to fasten it to the jamb lip.

Step 6: Once you are satisfied with the placement of the panel, it is time to screw it in place. Use the provided #6 sheet metal screws. Do not place the screws close to the glass. If a screw hits the pet door glass or the sliding door glass, it will break.

Step 7 (omit if you are installing on the stationary side): The lock strip will be screwed to the leading edge of your slider. Be very careful installing the screws. The latch bar which mates with the lock on the panel must face the inside of the house.

Step 8: Apply the provided vinyl weather stripping to the back edge of the slider or the front edge of the stationary panel. This will eliminate any gaps created by overlapping glass.
