To the central portion of the sliding bolt a rack bar is secured, in mesh with the pinion operated by the cylinder of the lock. The said rack bar acts as an abutment member in cooperation with the lock casing in order to limit the sliding movement in both directions of the sliding bolt. Means are provided for fastening the said lock to a rolling gate by using nuts and bolts.
