Abstract
A release mechanism for protecting a sectional door under impact allows one or more door panels to breakaway from its guide track without damaging the door. The release mechanism includes a snap-in pin that can be selectively repositioned to provide various operating modes. Examples of operating modes include unidirectional release, bi-directional release, and a disabled mode. In some cases, the breakaway threshold is greater in one direction than another. In the disabled mode, the release mechanism is not meant to release. Some embodiments include a door locking mechanism that still allows the release mechanism to operate.
