For use with an industrial door for selectively blocking and unblocking a doorway having guide members disposed on opposite sides thereof, an assembly comprising in combination:a first resilient member disposed adjacent a leading edge of a door curtain, the first resilient member being substantially untensioned when no external force is applied to the door curtain and being adapted to at least partially conform to or at least partially deflect about encountered obstacles; andguide extensions coupled to either end of the first resilient member, each of the guide extensions being adapted to engage a respective one of the guide members to guide the movement of the door curtain;wherein the first resilient member becomes tensioned upon application of an external force directed opposite a direction of movement of the door curtain and in a plane of the door curtain and of a magnitude greater than a first predetermined threshold.
