This is a very large hook and can carry a lot of weight. It weighs 2 1/4 pounds. It has rusted through the years, but we have left it as is.
The top arm extends 12 inches from the back plate, and the lower arm projects 4 inches from the base.
The back plate, with four screw holes, measures 5 inches vertically and 2 1/2 inches across.
Hooks of this size and age are very hard to acquire.
