This tandem roller assembly is a replacement part for a sliding patio glass door. Features an adjustable housing with steel tandem ball bearing wheels. Wheels measure 1-1/4" in diameter and are concave; the housing measures 13/16" in width.
Helpful Tip!
This part does not include new fasteners. Do not throw away your original screws, you will need them for the installation of your new part.
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.
