This replacement steel sliding patio glass door roller assembly is used on panels produced by Harcar, Crown, as well as many other manufacturers. It features an adjustable concave ball bearing wheel with a 1-1/2" diameter, 5/16" wide. The housing dimensions: 3/4" width; 13/16" flare width; 1-9/16" height.
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.
