Parts

  • Monorail Adapter
  • 2 10-24 x 1-1/8" Stainless steel screws
  • 2 10-24 Stainless Steel Acorn nuts

Tools

  • Drill with a 3/8“ bit for drilling metal
  • Clamps

Compatible Panel Models: Endura Flap Aluminum Thermo Panels. The monorail adapter installation requires two people. Please review the installation instructions included with your panel to familiarize yourself with the installation guidelines.

Please Note: Before drilling into your panel, test fit which side of the monorail adapter (1” or 1-1/2") depth will fit over your track the best without any gaps.

Step 1 Test Fit the Adapter

  • Test fit the adapter on your monorail track to determine which side fits your monorail height the best (1” or 1-1/2").
  •  
  • The opposite channel will hold your pet door panel.
  • Mark the side for the panel so you can properly drill the holes.

Step 2 Lay the Panel Flat

  • Lay the panel on a table with the Height Adjustment Locks facing up.
  • Clamp it to the table.

Step 3 Drill the Holes

  • 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 Apply Weatherstripping

  • Remove the panel from the table. Remove the clamps, holding the adapter to the panel.
  • Apply weather stripping to sides of panel (included upon the purchase of your panel).

Step 5 Position In Slider Track

  • 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.
  • 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 6 Screw Into Place

  • With the second person still holding the panel, gently lower it until it is resting on the adapter pieces, and the adapter channel is resting on the sliding door track.
  • Put the two screws through the holes and screw the cap nuts on (or nuts with protective caps).
  • Double check to make sure that the screw end is not protruding and there are no sharp edges sticking out.

Step 7 Release Height Adjustment Mechanism

  • Gently release the Height Adjustment Locks so that the height adjustment piece rises into the upper track.
  • Tighten the Height Adjustment Locks to affix the top tension adjustment piece in place.
  • Assure that the panel is stable and fixed in place. Then have the second person release the panel.

FAQ

Does this work for every brand of pet door insert?

No, this monorail adaptor is made specifically for Endura Flap and Sureflap Thermo Panels. It does not work for Endura vinyl panels.

How do I tell if my sliding glass door has a monorail track or not?

If your track is elevated above floor level, it is a monorail track. The Thermo Panel is made to slip into recessive sliding door tracks with the sides of the track holding the panel in place. The adapter mimics recessive sliding door tracks so that the Thermo Panel will stand upright.

Will the adapter make it harder to install my pet door?

It depends on how handy you are. The adapter must be installed into the bottom of the Thermo Panel, which requires drilling and other tools. You can review the installation instructions to see if it matches your skill level. If not, we recommend getting in contact with a professional.

Will the monorail track adapter break my apartment’s security deposit?

While the Thermo Panel can normally be installed tools-free, the monorail adapter requires you to screw the panel into your sliding door way. It is only a few screws that can easily be removed at the end of your lease. It is best that you check in with your landlord to see what is allowed in your apartment or not, but as is, the monorail adapter requires your Thermo Panel to be semi-permanently installed.

How do I know what size to get?

You need to order the size that corresponds to the size of your pet door flap. For example, if you ordered a small Endura Flap pet door, you should order the small monorail adapter.

Monorail adapter

The adapter works well once installed. However, it was not an easy installation. The parts need to be machined as Front and Back so the drill holes align because it was hard to drill through all layers and get them aligned properly. Also, if you don't clamp it down very securely to drill, it will shift and not align correctly on the door. Because of these two issues I'm only giving it three stars.

Great in the summer

I’m actually going to comment on the whole door. As we live in Canada and have a lot of minus temperatures in the winter, the door is not appropriate for these conditions. Since it is so cold, there is condensation on the steel on the inside of the door and there are still areas around the flap that you can feel the wind coming through even though it’s insulated. That being said, we have no issues taking it out for the winter. It still was a great purchase! Scott is also one of the best customer service person I have ever spoken to. He went beyond to help me get the perfect door. Thanks
