Overview
A large adjustable plastic dog and cat door sized for a 20 x 13.31 x 4.45 inch opening, finished in white and grey. It weighs 4.9 lbs and ships with the screws needed for mounting.
This is the large counterpart to Amazon Basics' small pet door, built for a bigger opening rather than the 4-way lock called out on the small size. The listing emphasizes easy installation over any locking mechanism.
- 20 x 13.31 x 4.45 inch opening
- White and grey finish
- 4.9 lbs
- Screws included for installation
Who it's for
Owners of larger dogs or multiple pets who need a bigger opening than a small or medium door provides. Not the right pick if you specifically want the adjustable 4-way locking found on the smaller size.
Pros and cons
- Large 20 x 13.31 inch opening for bigger pets
- Mounting screws included
- Straightforward installation per the listing
- Listing doesn't call out a 4-way lock like the small size
- Heavier and larger footprint to install
Performance notes
At 20 x 13.31 x 4.45 inches, the opening is sized well beyond the small version, and the listing highlights easy installation with the included screws. At 4.9 lbs, it's noticeably heavier than a typical small flap door, consistent with its larger panel size.
