Storm Door Torsion Springs


Style 1	Style 2

Mounted diagonally so one end is higher than the other, the motion of an opening door tightens the torsion spring; as it unwinds, it closes the door.

For Door Swing Direction—They are reversible for right or left door-swing directions.

Overhead Door Spring Winding Rods

Keep your overhead door balanced on both tracks for smooth, even opening and closing. These winding rods help you safely increase and decrease the tension on the springs that hold the door. Their ends are machined to fit snugly into the springs' tensioning holes, giving you good control and preventing these rods from slipping out as you tension. Use these rods in pairs. For better leverage and easier winding, choose longer rods.
