Sea-Dog Strap Hinge, 4 Inch 304 Stainless Steel Surface Mount, Part 201134-1

The Sea-Dog Strap Hinge (part 201134-1) is a stamped 304 stainless steel hinge built for surface-mounting applications where hardware is exposed to the elements. It consists of two long, narrow leaves extending from a single knuckle, a design that spreads mounting screws over a longer span for a stronger hold on lids and panels that see frequent use. This hinge is commonly used for dock box lids, fish holds, and similar outdoor marine storage where corrosion resistance and repeated opening and closing are everyday requirements.

Constructed from corrosion resistant stamped 304 stainless steel, this strap hinge holds up to saltwater spray, sun, and general marine exposure better than painted or plated steel alternatives. It installs with #8 flat head fasteners, which are not included, so any standard #8 FH screw compatible with the mounting surface will work. Overall length is 4 inches, with each leaf measuring 2 inches wide, a 1-1/8 inch knuckle diameter, and 1/8 inch material thickness, giving it a compact footprint suited to dock boxes, hatch lids, and storage compartments. It is sold in packs of 10 hinges (10 pairs).
