Abstract: A gate latch assembly includes a pair of cover members having a common plane of symmetry. A first cover member defines a recess receiving an adjoining lever and spacer block, each having its own plane of symmetry perpendicular to the cover plane of symmetry. The spacer block includes a pair of recesses on opposing sides of the block at one end thereof for receiving the lever on either side of the block. The remaining cover member closes the recess and defines another recess with the first cover member for receiving a portion of a gate or other swinging member on which the gate assembly is mounted. The symmetry of the assembly permits it to be used for left-handed or right-handed and inside or outside opening. A preferred hinge includes a pair of identical post leaves and a gate leaf. Each post leaf includes a knuckle and a post plate supported tangentially from the knuckle by an extenison portion.
