Sea-Dog Stainless Steel Butt Hinge 205140-1, 1-5/8 x 1-1/2 Inch

The Sea-Dog 205140-1 Butt Hinge is a compact marine-grade hinge built from investment cast 316 stainless steel, chosen for its resistance to corrosion in saltwater and humid marine environments. It consists of two rectangular leaves that attach to the abutting surfaces of a door and door jamb, typically mortised into each surface and joined together by a hinge pin for smooth, reliable swing action.

This hinge is sized for smaller doors, hatches, lockers, and cabinets aboard a boat, or for comparable marine cabinetry applications ashore. Each leaf measures 1-5/8 inches (dimension A) with a 13/16 inch dimension on both the B and C measurements, an overall D dimension of 1-1/2 inches, and a leaf thickness (E) of 3/16 inch. It installs using four #10 flat head fasteners, which are not included, allowing the installer to select fastener length and finish to suit the mounting surface.

Because it is cast rather than stamped, the hinge holds its shape and pin alignment under repeated use and resists the pitting and rust that can affect lower-grade hardware over time. It is sold and packed as a single hinge unit.
