Tandem Roller Assembly, 1-11/16" Nylon Concave
Product Code: 81-171
This replacement roller assembly is for a sliding patio glass door. Features an extruded aluminum housing with a built-in nylon track cleaner and stainless steel adjustable inner housing with two 1-11/16" diameter nylon concave wheels with stainless steel ball-bearings. Used in doors manufactured by Alcan, Norandex, and others.
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.
