Are you having trouble sliding your screen door open or closed? Have you checked your rollers/roller assemblies? Don’t replace the entire door. For a fraction of the cost of a new door, replace those worn-out rollers. This Andersen roller assembly is an insert style with mounting tabs and included installation screws. The high-density polyethylene housing has an aluminum inner housing with a 1 Inch high density stainless steel roller. This roller assembly was used on the 200 Series Perma-Shield gliding doors and 400 Series Frenchwood doors. Height adjustment is down from the side rather than the top or the edge of the door. Order yours today and have your door slide like new.
