Question:

Which models of Fulton F2 jacks have a bolt pattern of 3 1/2 x 4 1/2? I am taking off my current F2 and replacing. Do you know any other marine jacks that would also have the same bolt pattern?

The Fulton F2 Swing-Up Trailer Jack you referenced, part # F1413040134, has according to my contact at Fulton a bolt pattern of 3.44 inches X 4.44 inches measured precisely from hole center to hole center, top to bottom and side to side, respectively. This hole spacing may sometimes be referred to as 3 x 4 inches for convenience.

I pulled a sample of the matching mounting plate that we offer for weld-on installations, part # F500277, and measured the hole spacing on this part. Although this item is labelled as a 3 X 4-inch mount, it actually does measure 3.44 X 4.44 inches as per the manufacturer. It will also commonly be referred to as a 3-1/2 x 4-1/2 mounting pattern!

For reference I have linked a page showing all Fulton bolt-on swivel jacks. Some of these are bolt-thru types and others mount around the trailer frame using supplied U-bolts.
