    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.
