A mounting bracket (10) for mounting items (I) on a metal post (P) located on a boat dock (D). A support member (12) allows a user to position the bracket where an item is to be mounted on a post with a pair of clamps (14a, 14b) then being used to affix the item to the bracket. The support member has a set (13) of teeth (T) formed at each end (12e) which bite into, but do penetrate through, the post. When the clamps are attached to the support member, tightening down of the clamps causes the teeth to bite into the post to hold the mounting bracket securely in place, but this does not result in holes being made in the side of the post which might later result in corrosion.
