Product Details

A door-mounted pet door should feel like part of the home, not an afterthought. This design is built for homeowners who want convenient pet access without giving up the comfort and control of their living space. 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
Fit and performance can be tailored to your setup. The door is available in single and double flap configurations, and magnet strength can be adjusted to balance ease of use for your pet with the level of seal needed for your climate. This flexibility helps the door perform well across a range of conditions and pet behaviors.

Built for the Long Term
Built in the USA and backed by a lifetime warranty, this is a solution designed for long-term reliability, consistent performance, and a more refined everyday experience.

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
