About This Product

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 is a tension spring roller assembly, with a downward offset tension spring used by Academy and a variety of other sliding patio door manufacturers. The roller is a 1 Inch high-density polyethylene roller with a 1-3/4 Inch long tension spring that is a heat treated steel spring. When installed the bent, or angled, flat spring positions the roller assembly so that an adjusting screw adjusts the height of the roller as needed. For stainless steel roller assembly use Prime-Line part B 756. Order yours today and have your door slide like new.

Highlights

  • Used by Academy screen doors and a variety of other sliding screen door manufacturers

          The tension spring was the same type installed bottom of sliding screen patio door. The old tension was defective causing screen door not close and open properly being off track. Installed a new set tension springs.
