Prime-line B 639 Screen Door Roller Assembly, 1 In., 2-pack

This tension spring roller assembly is designed for sliding screen and patio doors, including those manufactured by Academy and other door makers. The roller assembly maintains consistent movement of screen doors while allowing for height adjustment to ensure proper alignment and operation. Whether your screen door needs a replacement roller or the assembly requires servicing, this two-pack provides the components needed to restore proper door function.

The assembly uses a V-spring design with an offset bend that positions the roller and permits fine height adjustments via an included adjusting screw. The 1-inch diameter concave roller features a center groove, while the 1-3/4 inch high-tension, heat-treated steel spring and ball bearing roller are engineered to work together for smooth operation.
