What type of springs for a 9x7 door?

A 9x7 garage door does not have one standard spring size. It may use a torsion spring mounted above the door or extension springs that run alongside the tracks. The correct spring depends on the door’s weight and track setup, as well as the spring system already in place. Insulation, windows, and other features can make two doors of the same size weigh differently.

If a spring breaks, choosing a replacement based only on the door’s dimensions can leave it poorly balanced and put extra strain on the opener. Our technicians inspect the system and select a spring suited to the door. Garage door springs are under significant tension, so replacement should be handled by a trained professional.
