Patio Roller Assembly, 1-1/2" Steel Concave BB
Product Code: 81-255
This replacement roller assembly features an adjustable housing with a 1-1/2" diameter steel concave ball bearing wheel. This roller is used in sliding patio glass doors manufactured by Window Master and other manufacturers.
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.
