This is the larger version of the Boat Cover Socket for a Bow Slate. This socket is the Heavy Duty version. I used the same picture for this as I did the Light Duty Version because, they look almost the same. The metal part of the Heavy Duty version is a little larger and more bulky. The inside hole is still the same size and is 1 3/4" long and 1/2" wide. It is 2 3/4" from screw hole to screw hole.
