Mechanism of Extension Spring Lift
A pair of extended springs running parallel to the horizontal rails make up an extension spring counterbalance system. The b&d garage door opener is lifted by springs that go through a system of pulleys and counterweight cables that extend from the bottom corner brackets to the pulleys. The springs compress as the door is raised, raising the door when the tension is released. These springs are typically constructed of 11 gauge galvanised steel, and their lengths are determined by the height of the garage door. The colour of the paint on the ends of the springs best identifies their lifting weight capacity.
