ABSTRACT:
A security lock for movable closure and, more particularly, for horizontal slider windows in which a case for the lock has a top wall and side walls defining a generally hollow interior opening to the bottom of the case, a bolt is movably mounted in a channel formed within the case with the channel opening toward the bottom of the case. The bolt is movable between extended and retracted positions. Structure for positioning of the bolt includes a driver associated with a manually-rotatable shaft and a connection between the driven and the bolt which functions to retain the bolt from falling out of the guide channel through the open bottom of the case during handling and shipping and to also transmit movement of the shaft to the bolt.
