  • Channel attachment for monorail sliding glass doors
  • Fits over tracks 3/4" wide by 3/4" high
  • Available in white, bronze, or satin to match your door
  • Work for Endura Flap and SureFlap models only
  • Screws not included

All of the Endura Flap panels are designed to fit into recessed tracks. However, since many sliding glass doors now have a raised track, we've designed a new monorail track adapter for panels to accommodate every need. The adapter provides a channel for the panel to fit in, ensuring that your Endura Flap door is stable. This adapter works for the Endura Flap small through extra-large sizes, as well as the SureFlap Pet Door and Dual Scan/Cat Flap.

Additional Notes:

  • The adapter comes with guide holes pre-punched, but you will need to drill the finish holes through the panel
  • Additional screws will need to be purchased. Once the adapter is fitted onto the bottom, the total thickness of the panel will be 1". Make sure the screws purchased will have a little extra length in order for a rounded cap nut to fit over them
  • This part is only for Endura or SureFlap panels” it will not be compatible with any other model or manufacturer.

Installation Instructions


  • Drill with a 3⁄8“ bit
  • 2x 1 1⁄4" screws
  • 2x nuts
  • 2x screw caps
  • Clamps

Please Note: Please review the installation instructions included with your panel to familiarize yourself with the installation guidelines. This installation requires two people.

Step 1: Lay the panel on a table with the thumbscrews facing up. Clamp it to the table.

Step 2: Take the adapter side with the pre-punched holes and line it up on the bottom of the panel, facing up. Take the second piece and put that on the back side of the panel, clamping both pieces to the bottom of the panel.

Step 3: With the end of the panel hanging slightly off the table, drill the holes straight through the panel and adapter pieces (all the way until the drill bit punches through the other side of the adapter).

Step 4: Remove the panel from the table. Remove the clamps, holding the adapter to the panel.

Step 5: Apply weather stripping to sides of panel (included upon the purchase of your panel).

Step 6: Have one person hold the panel in place over the monorail track, leaving at least ¼” of space between the bottom of the panel and the track.

Step 7: The second person needs to slide the adapter pieces together onto the inside and outside face of the patio panel so that they overlap and sandwich the panel and track.

Step 8: With the second person still holding the panel, gently lower it until it is resting on the adapter, and the adapter channel is resting on the sliding door track.  Put the two screws through the holes and screw the nuts on. Put on the protective screw caps.

Step 9: Double check to make sure that the screw end is not protruding and there are no sharp edges sticking out.

Step 10: Gently release the thumbscrews so that the height adjustment piece rises into the upper track. Tighten the thumbscrews to fix the top tension adjustment piece in place.

Step 11: Assure that the panel is stable and fixed in place. Then have the second person release the panel.
