Abstract
A lock having an optional bolting member is described. It includes a lock case having opposed walls and a latch bolt slidable between a locking position and an unlocking position. The optional bolting member includes a holding bolt introducible through an aperture provided in at least one of the opposed walls. The holding bolt is positionable in a first, relatively retracted position allowing sliding of the latch bolt from its locking position to its unlocking position, and in a second, relatively inserted position preventing sliding of the holding bolt from its locking position to its unlocking position. The optional bolting member further includes a biasing member for yieldably retaining the holding bolt in its first and second positions.
