Top "H" Section Spring Loaded Bar and Adjustment Knob for Aluminum Pet Patio Doors.
Sold Individually.
To determine the correct size door, simply measure the width (A) and height (B) of your pet.
(A) Measure the widest point of your pet's shoulder.
(B) Measure from the top of your pet's back (just behind their head) to the bottom of chest.
Pet door models have different size openings. Just make sure your new pet door's opening is both wider and taller than your pet's measurements to ensure they can comfortably pass through.

Difficult to install
We ordered this product to replace rusted springs on our door. It was so difficult to install we ordered a new door. We were also unable to return the item at a low cost.
