Slide-Co 1 In. Nylon Screen Door Roller with Steel Ball Bearing Straight Spring Tension Assembly (2-Count)

High tension steel spring roller assembly fits onto the Columbia Uni-Fit series door. This roller assembly has a 1 inch high density polyethlene roller mounted in the housing. The flat steel spring end catches onto the inside of the door frame while the flat edges of the 2 tabs extending out in front of the roller restrict the roller from retracting too far up into the door frame as it rolls.
