Product Description
This spring tension replacement roller is for sliding screen patio doors and features a metal housing with a nylon concave wheel. Used on Columbia Uni-fit doors. The wheel measures 1" in diameter and 1/4" thick.

Good Idea!
The typical patio sliding screen door uses two roller assemblies, one on each bottom corner of the sliding door. We recommend replacing both sliding door rollers at the same time to prevent extra wear-and-tear to one new roller, which will have to work twice as hard when paired with an old roller.
