Abstract
A latching and locking mechanism for sliding doors such as patio screen doors and the like, wherein a latch hook engaging a keeper may be unlatched by operating either an inside or an outside slide member, and the latch hook may be locked by a locking mechanism operable only from the inside of the sliding door. The latching and locking mechanism is lengthwise functionally symmetric so that it may be utilized either in doors opening from left to right or doors opening from right to left. The locking function is performed by a locking bolt which is cammed into position by an angularly disposed cam slot of a bolt actuator.
