This is a Heavy Duty Version of a Swivel Top Bunk Bracket. This Hot-Dipped Galvanized Swivel Top Bunk Bracket will replace rusted out Swivel Tops on your Bunk Brackets. These Heavy Duty Swivel Tops are meant for mounting 2 inch by 4 inch Bunk Boards at a specified angle to support the hull of your boat. This Heavy Duty Hot-Dipped Galvanized Swivel Top Bunk Bracket is made of 3/16 inch steel, measures 3 1/2 inches long x 2 inches (side with 1 hole) x 1 1/4 inches (side with 2 holes). The Top holes measure 2 1/2 inches center to center.
We have the needed lag screws and stainless steel mounting bolt available as add ons to this item. This thicker version of top bracket is also common on 2" x 2" vertical swivel brackets. If you are needed this top for that purpose, you may be needed a longer 1/2" diameter bolt to go through the 2 inch tubing. In some cases, we would also see a pair of these on each square vertical support bracket.
