Extra Large Dog Door Replacement Flaps 2PACK - Flexible Weather

In this review the MOLYLY 2PACK Extra Large Dog Door Replacement Flaps are examined for owners who need a direct, affordable replacement for a worn or cracked flap. The review focuses on fit, durability and ease of installation because those are the decisive factors for replacing a doggie door flap. These flaps are marketed as compatible with PAC 11-11040 style doors and measure 13 1/8' x 24 7/8', and the single biggest reason to consider them is the simple, screw-down installation that restores a sealed, flexible passage without modifying the existing frame.

Key Features

• Compatibility: Sold as a 2 pack designed to match PAC 11-11040 style openings so customers can replace both flaps or keep a spare for later.
• Exact size: Measures 13 1/8' wide by 24 7/8' high to provide a close fit to the original opening and minimize trimming or adjustments.
• Durable material: Made from flexible, durable material that resists everyday wear and allows pets to push through easily.
• Weather resistance: Wind and rain-resistant design helps keep the interior drier and reduces drafts compared with torn or warped originals.
• Easy installation: Includes screws and installs with basic tools, letting owners replace the flap quickly without replacing the whole frame.
• Pet comfort: Smooth flexible material and full-size opening enable comfortable, low-effort access for most dogs.

Who It's For

The 2PACK replacement flaps are best for dog owners who already have a PAC 11-11040 style dog door and want a like-for-like replacement that restores function without professional help. It suits households that value quick DIY fixes, need weather resistance, and prefer keeping a spare on hand for future wear.

Owners with nonstandard or significantly altered frames should verify measurements before buying, and those needing heavier, reinforced flap material for very large or especially active dogs may want to look for thicker commercial-grade options instead.

Frequently Asked Questions

Will these flaps fit my existing PAC 11-11040 frame?
They are made to match PAC 11-11040 style openings at 13 1/8' x 24 7/8', but you should measure your frame as some users report the height can be about 1/4' different.

Are screws included for installation?

How weather resistant are these flaps?
The material is designed to resist wind and rain better than a torn flap, helping reduce drafts and interior wetting, though very harsh climates may shorten service life.
