Abstract
An overhead roll door includes a breakaway guide follower having a first part attached to a raising and lowering mechanism and a second part attached to the door. The first part defines a pivotable latch plate having a slot therein, and the second part of the guide follower defines a pin received in the slot. A detent mechanism resists rotation of the latch plate out of a retaining position, in which the first and second retaining elements are held together, to a release position, in which the second retaining element is allowed to move transversely with respect to the first retaining element to allow the door to breakaway in response to an impact.
