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