Product Description
This replacement roller is for sliding glass patio doors and features an adjustable housing with a steel concave ball-bearing wheel. Used on Acorn Series 800 doors, Arundel doors as well as other manufactured doors.

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.
