Product Description
This replacement roller is for sliding patio glass doors and features a metal housing with a steel concave ball-bearing wheel. The top center hole is machine threaded 10-32". Features an adjustment screw to lower and raise the wheel. Used on doors manufactured by Air Control, Krestmark, Howmet and others.
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.
