Each helical torsion spring is engineered & made-to-order on our service fleet, to ensure proper spring balance. Central State springs are available with up to 100,000 cycles of use and are a step above the rest. Not just heat tempered, these springs are treated with a secondary coating* and reheated to resist corrosion. *Coating available up to 3.75" I.D.

A frayed, compromised, or broken lift cable can be extremely dangerous. Most cables are manufactured to handle the minimum load possible of an overhead door; ours are made using thicker, stronger braids, and can handle the maximum potential load of an overhead door. We stock 1/4", 3/16", 5/32" and 1/8", with a break strength of up to 7,000 pounds. Our selection of cables ensures we always have the proper cable for your doors.

On an overhead door the hinges bear a tremendous amount of weight. Central State’s hinges exceed industry standards with 11 gauge heavy duty steel and have 75% more surface area than the leading competitor to provide maximum safety and product integrity.
