Why You'll Love It

This dog door balances independent pet access with features designed for household comfort and access control. The insulated flap system helps reduce exposure to outside air, while the aluminum frame provides a sturdy structure for regular use.

• Improved sealing: Three flaps, brush seals and a magnetic bottom closure work together to help reduce unwanted airflow.
• Controlled access: Interior locking mechanisms allow the opening to be secured when needed.
• Serviceable design: The included spare flap provides a replacement when the working flap wears out during regular use.

Three-Flap Insulated Design

The door uses three flaps with an added insulation layer to help block cold outside air during winter and heat during summer. Side brush seals complement the flap system by helping reduce gaps along the edges.

A strong bottom magnet helps bring the flap back into a snug closed position after use. Together, these features are designed to minimize drafts, dust and wind rather than creating a completely airtight barrier.

Aluminum Construction & Locking

The frame is made from aluminum alloy and reinforced through welding for added structural stability. Aluminum provides a lightweight structure while offering resistance to rust and paint chipping in outdoor conditions.

Two aluminum locking mechanisms secure the panel from inside the home. This gives you a straightforward way to restrict passage through the pet door when independent access is not desired.
