Product Description
This replacement sliding patio glass door roller assembly features an adjustable housing with a 1-1/2" steel concave ball-bearing wheel. Used by several patio door manufacturers.

Good Idea!
The typical patio sliding glass 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.
