Abstract
A system for allowing a loading dock door to release from guide tracks. The dock door includes wheel-and-axle assemblies which are mounted to the door and which include wheels biased towards a position in the tracks. At least one of the tracks has a cross sectional profile which enables the wheels disposed in the one of the tracks to move out of the one of the tracks when the door is struck with sufficient force.
