ABSTRACT:
A door operator system includes a rodless fluid cylinder that has a cylinder body and a rodless piston adapted for reciprocation in the cylinder body. A carriage which is adapted for reciprocation externally along the length of the cylinder body is secured to the piston. An arm member connects the cylinder carriage to an associated sliding door. A control circuit is provided for controlling the operation of the fluid cylinder and hence the position of the associated sliding door.
