Abstract
The disclosed invention prevents damage to a hood and its contents. In a preferred embodiment, a first and second support member are mounted on either side of an access opening. A cross member is slidably retained in a protective, starting position within the support members. The cross member is preferably positioned above the access opening in front of a coiling door hood such that a striking force directed at the hood first encounters the cross member. When struck, the cross member slidably retracts against a force assembly to dissipate the striking force and upon withdrawal of the striking force the cross member returns without human intervention to the protective, starting position.
