This is new-old-stock. The cupboard latch is a full-mortised latch with a turn knob and strike plate.
The latch is a cylinder insert that is 1 1/2 inches long and 1/2 inch in diameter. The back plate behind the turn knob, that mounts on the front of the door, measures 1 7/8 inches long and 7/8 inch wide. The knob is one inch by 1/2 inch. The latch has a bronze finish.
A strike plate and screws are included. This latch is new, but has been un-used and “on a shelf” for many years. We were fortunate to find a few of these made-in-the-US latches.
