        Questions

        Does this locking nut "unlock" by turning it clockwise instead?

        Asked by: Ryan
        The nut loosen, or unlocks, by turning it counterclockwise. For a thru hull fitting, you should use a backing plate.

        What size socket will fit the 1 1/2 inch lock nut?

        Asked by: Psquare
        I used a large adjustable wrench.
