Extra-Stretch Extension Springs
These fabric-covered rubber springs stretch up to three times their original length—much farther than traditional extension springs, tie downs, and shock cords. All have carabiner ends with spring-loaded latch openings. Do not use to hold overhead loads.
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch of extension.

Winding Rods for Overhead Door Springs
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.
