Product Details

Product Details

This Door Mount model is designed specifically for doors where standard pet doors are too deep to fit properly. It provides a clean, stable installation in thinner door panels, making it a practical solution for interior doors, garage doors, and other narrow constructions.

Magnets along three sides of the flap help it return to a closed position after each use, creating a more consistent barrier against wind and outside air. This added control helps maintain a more comfortable environment near the door, even in changing weather conditions.

The flap is constructed from a polyolefin-based polymer that stays responsive across a wide range of temperatures. It remains flexible in cold conditions and resists deformation in heat, allowing pets to move through easily while maintaining proper closure.

The aluminum frame provides a durable structure that holds up over time, even with frequent use from active pets. The taller, narrower flap shape supports a variety of pet sizes while maintaining a balanced, functional design.

A locking cover is included to secure the opening when the door is not in use. The construction provides a more substantial barrier, giving added control over when and how the pet door is used.

Magnet strength can be adjusted to better match your pet and environment. This allows for an easier push-through for more hesitant pets while still maintaining a reliable seal when conditions require it.

Made in the USA and backed by a lifetime warranty, this pet door is built for consistent performance and everyday reliability in homes that require a thinner door solution.

Step 1 Prep Your Door

Prep Your Door
  • If you have not yet measured your pet, watch this video to ensure the pet door will work.
  • If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flap for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 3" above the pet's shoulders.
  • Be careful not to cut too close to the bottom of the door as you may reduce the door's strength. Level the top edge of the cut-out line.

Step 2 Drill the Holes

  • Once you are certain the pet door will work with your door, make sure the template is level, and mark the outline with a pencil. Remove the template and drill holes through the corners just inside of the lines using a 3/8" drill bit.
  • Make sure your drill is kept level and drills all the way through the door.

Step 3 Saw An Opening

  • We recommend applying masking tape along the outside of the lines to protect your door from scratch marks as you cut with the jigsaw.

Step 4 Check Weatherstripping
