Product Overview
Tension spring roller assembly with a V spring design used by Academy & other patio door manufacturers. The roller is a 1 inch 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.
