Abstract
Hardware designed to improve safety and minimize the risk involved in installing, maintaining, and operating sectional doors that use spring mechanisms to facilitate door movement. A lock-on side bearing bracket bears up a spring mechanism on a garage door. This side bearing bracket includes a hook and a perpendicular tab to prevent the spring mechanism from dangerously releasing its energy when parts supporting the spring mechanism are removed or fail. A lock-on bottom roller bracket having a bottom bearing plate and a safety hook similarly prevents a potential, dangerous release of energy when the garage door lift cable is in tension. A safety latch with a latch bar and a latch cover acts as a lock for the garage door. The use of multiple safety features makes the garage door systems of the present invention particularly safe to operate and maintain.
