This hinge was manufactured by the Ajax Hardware Company in California sometime from the late 1940s through the 1950s. This one has an Art Deco look. The cabinet hinge has an inset of 3/8 inch to accommodate a cabinet door that was mounted (or hung) by a hinge wing on the backside. The narrow plate and spine are fastened to the frame while the door butts up to the frame and is fastened into place from the back.
The narrow frame wing measures 2 1/2 inches long and 3/8 inch wide. The surface off set is 3/8 inch wide. The hinge wing that fastens to the back of the door measures 1 1/4 inches horizontally and 1 1/2 inches vertically.
screws will be included.
