ABSTRACT:
A sliding door operator comprises a tubular housing adapted to receive first and second elongated bars in a spaced apart and parallel arrangement. Both bars include a gear-toothed rack engaged by a single motor driven gear. An end of one bar is secured to the door and an end of the other bar is secured to a wall structure. A bracket secured to the door includes registering apertures adapted to mate with a bore in the end of one of the bars so that the bar can be detachably locked to the door by a locking pin. The other bar also includes a bore adapted to mate with the aperture in a channel bracket secured to the stationary wall structure to receive a removable locking pin therethrough. In addition, the operator includes a locking mechanism for locking the bars in a fixed position with respect to each other.
