ABSTRACT:
A roll-up door operable to slide between tracks by using an operating mechanism having a handle which extends substantially the width of the door. When the handle is pushed, it pivots in a housing attached to the door to an actuated position so that a latch at the end of the handle is retracted clear of a slot in one of the tracks. A spring is also provided between the handle and the housing for biasing the handle to pivot to a relaxed position where the latch is engaged in the slot in the track. The operating mechanism also has a lock which can be turned to position a lock bar between the handle and the housing so that the handle cannot be pivoted to the actuated position.
