How does the PetSafe door help in hot and cold weather?

The three-flap system includes a center insulated flap and is designed for temperatures from -10°F to 100°F (about -23°C to 38°C). PetSafe rates it 3.5 times more efficient than a single-flap door, with the additional flaps helping to keep extreme warm and cool air outside the home.

• The center flap provides an added layer of insulation.
• The efficiency rating compares this door with single-flap doors.

What doors does the large model fit?

The large model is designed for do-it-yourself installation in standard-size paneled, wood, metal, and PVC doors. The door panel must be 1 5/8 in–2 1/4 in thick (4.1–5.7 cm), so compare that measurement with your door before installation.

• Installation is a DIY project.
• The plastic frame is white and paintable to match your door’s existing color.

How can I control my pet’s access?

A snap-on closing panel can block your pet from using the door when you want to limit access. A second closing panel is sold separately and adds another layer of weather protection.

• Use the closing panel to restrict passage through the pet door.
• PetSafe offers U.S.-based pet-product expert support by phone, email, and chat.

This door suits households looking for a DIY pet-access option that fits compatible standard-size doors and is designed for hot or cold climates. PetSafe’s three-flap construction, insulated center flap, and access panel bring weather-conscious pet passage and access control together.
