Title: Spring retainer for garage door hardware

Abstract: A retainer to restrain pieces of a coil spring from scattering when the spring breaks under tension makes use of two mutually slidable elements located within the interior of the coil spring. Adjacent ends of the elements have a sliding engagement with each other and include a yieldable cushion inherent in the structure to absorb the impact when the spring breaks. The respective opposite ends of the elements are attached, one to the spring keeper at one end of the spring and the other to the spring keeper at the opposite end of the spring.
