Product Description
This roller assembly is a replacement for a sliding patio glass door; features an adjustable extruded aluminum housing with a stainless steel concave ball bearing wheel; measures 1-1/2" in diameter.

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.
