Abstract
An industrial door includes a door panel that is movable between an open position and a closed position where the door panel encloses a doorway. A flexible beam is attached to the lower edge of the door panel and the beam is composed of superimposed strips of resilient material, such as rubber, with flexible metal strips disposed between adjacent resilient strips. Each end of the beam is provided with a longitudinal open-ended slot and an extension of a guide member is mounted within each slot in a manner such that the extensions will freely slide in the slots in a direction parallel to the plane of the door panel and will be released from the slots if the beam is subjected to a substantial accidental impact.
