Abstract
A roll-up door having a smaller service door therein is provided. The smaller service door pivots about a vertical hinged edge and enables an operator to move through the roll-up door more efficiently via the smaller and more convenient service door. According to one embodiment of the invention, a self-locking assembly is provided on the free end of the service door for holding together the free end of the service door so that it moves together as a single unit when the service door is in use. A method of manufacturing a roll-up door having a service door therein is also provided.
