This large PetSafe door is made for homes where pets need to go outside for potty breaks or play without waiting for someone to open the door. Its insulating flap system is designed for use through changing seasons, while the closing panel gives you a way to restrict access when needed.

How does the three-flap insulation work?

Three flexible flaps create an insulated passage, and the magnetic seal helps close the flaps against drafts. PetSafe says this design blocks 3 times more thermal energy than a standard pet door, making it the brand’s most energy-efficient pet door.

• Flaps are adjustable and flexible.
• The magnetic seal helps the flaps sit closed after pets pass through.

Which exterior doors can this pet door fit?

It is made to install in most exterior wood, paneled, PVC, and metal doors that are 1 1/2 in (3.8 cm) to 2 in (5.1 cm) thick. Installation is designed as a DIY project, so compare your door’s thickness with this range before choosing the large model.

How can I manage pet access?

Dogs and cats can pass through for outdoor breaks and play, while the slide-in closing panel lets you limit access when you want the opening closed. The frame is built for multi-pet households, and the door is intended to support pet independence without requiring you to open it each time.

• Designed for cats and dogs to move in and out.
• The included closing panel helps keep stray animals out when access is restricted.
