XL Replacement Dog Door Flap Fits PetSafe PAC11-11040 - Durable, BPA

In this review the XL Replacement Dog Door Flap from Best Pet Flap is evaluated as a practical, longer lasting alternative for owners who need a direct swap for flaps measuring 13 1/8' x 24 7/8'. The single biggest reason to consider it is durability: made with materials used in medical and food service industries and produced in Brazil, this flap promises greater weather resistance and less shrinkage than the original. For anyone replacing a worn PAC11-11040 style flap, this is a straightforward, environmentally friendlier option that installs quickly and aims to reduce drafts.

Key Features

• Superior replacement flap: Constructed to be more weather resistant than the original, helping reduce drafts and extend service life.
• Exact XL compatibility: Designed to fit flaps that measure 13 1/8' x 24 7/8', matching mounting hole layout for a direct swap.
• Environmentally friendly material: Not made with PVC and BPA free, offering a safer choice for pets and households concerned about chemicals.
• Longer lasting construction: Uses technology from medical and food service industries to resist wear and shrinkage over time.
• Quick installation: Installs in minutes with only a screwdriver, making replacement simple for most DIYers.
• Bottom magnet bar: Features a single magnet bar on the bottom to help the flap close securely and limit airflow.

Who It's For

This replacement flap is best for pet owners who already own a door system that used the PAC11-11040 sized flap and want a like-for-like fit without modifying their existing frame. It is also a good choice for buyers who prioritize materials that are not PVC and prefer BPA free components for pet safety.

It may be less suitable for people whose original flap shows a different mounting pattern or multiple magnets, or for those who prefer a heavy rubberized flap with a very stiff magnetic closure. Buyers uncertain about exact measurements should confirm the 13 1/8' x 24 7/8' dimension before purchasing.
