Abstract:
A dual action latch, having a latch handle, an elongate bolt, a cam, a latch housing, and a biasing device, for installation on one side of door. The latch handle includes a lifting portion and a lever arm. The latch housing has a lever arm aperture through which the lever arm of the latch handle passes and a bolt guide for slidably receiving the elongate bolt. The latch handle is movably attached to the latch housing. With the latch handle moved, the lever arm withdraws the elongate bolt into the latch housing. Independently, when the cam is rotated by a separate handle on the other side the door, the cam plate likewise withdraws the elongate bolt into the latch housing.
