Product Details

This Thin Door Mount model is designed, and built, specifically for installation locations where standard pet doors are too deep to fit properly. It's a great solution for thinner door panels, while also suitable for space separators, garage doors, or other narrow constructions. Once installed, it presents a clean, intentional look while supporting everyday use.

The magnetic sealing system plays a central role in that experience. Magnets along three sides help the flap return to a closed position after each use, creating a more consistent seal and helping prevent wind from pushing the flap open. This added control is especially noticeable during changing weather conditions.

Insulation That Works With Your Home
The flap itself is built with a dual-layer design that uses trapped air to slow heat transfer. Instead of behaving like a simple opening, the door maintains a more stable barrier between indoor and outdoor environments, helping reduce temperature swings near the entry point.

Security is addressed with a locking cover designed to provide a strong physical barrier when the door is not in use. The construction gives the door a more substantial feel and supports peace of mind when additional protection is needed.

Adjustable for Pets and Climate
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. While the thin door model features a single dual-layer flap, additional magnets may be purchased to maximize holding strength in very windy locations.

Built for the Long Term
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, visit our Size & Measurement Guide page 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
