Is there any limitation on the height of a roll-up door or sectional garage door that is tested with a given height?
Starting January 1, 1996 approval of Roll-up and Sectional doors shall be limited to three (3) times the height of the door tested. This is only applicable when the tested door does not have the top or bottom ends restricted. If the tested door has locks that engage on the floor, or vertical reinforcements, this does not apply; in this case the door shall be approved for the height tested.
