When a cabin door or deck hatch needs to handle years of daily use in a saltwater environment, the hinge is the last place to cut corners. This heavy-duty 316 stainless steel butt hinge is built with a thicker leaf profile and a mirror-polished finish that resists corrosion and maintains its appearance through seasons of offshore exposure. Available in four sizes to suit everything from small locker doors to full-size cabin entries on yachts and sailboats.
