Our standard platform support brackets are constructed of 1″, 16 gauge, polished 316 stainless steel tubing. The tubing is bolted to heavy-duty (11 gauge) 316 stainless steel fittings, which are bolted to the transom. The supports and platform can be removed for storage or for working on the transom, without disturbing the through-bolted fittings. Our deluxe support brackets are constructed of 316 stainless steel and are not removable. They are custom made to fit your boat and platform. All mounting hardware is included with our support brackets.
