Each pack contains two assemblies, each fitted with a 1-inch high-density polyethylene (HDPE) roller mounted in an adjustable HDPE inner housing. The flat steel spring end catches onto the inside of the door frame, while two forward-facing tabs prevent the roller from retracting too far into the frame during operation. The assembly inserts into the top or bottom of the sliding screen door frame using the included screws. This unit features a thinner HDPE frame profile compared to Prime Line part B 646.\u003c\/p\u003e\u003cp\u003eThis roller assembly is designed for use on Columbia Uni-Fit series sliding screen doors and is also compatible with a variety of other sliding screen door manufacturers that use a similar insert-style roller configuration. It is suited for residential applications where an adjustable, spring-loaded roller replacement is needed at the top or bottom of a sliding screen door.
