A roll-up or curtain type door is disclosed which has modular components which are interchangeable for use on either side of the door, thereby reducing significantly the number of parts which must be manufactured for the door. The number of hardware items is also reduced significantly by designing components which slide together in a secure locking fashion, resulting in better ease of assembly and installation. In one embodiment, the roll-up door of the present invention is used to secure a storage unit with shelves.
