Sea-Dog 90 Degree Deck Hinge, 3/4" x 2-1/4" Base, 316 Stainless Steel, Part 270200-1

The Sea-Dog 270200-1 is a 90 degree top mount deck hinge built for Bimini top applications, letting you attach an eye end fitting horizontally to a flat deck or gunwale surface. It is investment cast from 316 stainless steel, giving it strong resistance to salt water corrosion and long-term durability in a marine environment. The hinge has a 3/4" x 2-1/4" base footprint and uses a 1/4" pin size, matching the standard top mount hinge fittings in the Sea-Dog line. This is the fixed-pin version of the 90 degree hinge (a removable-pin version is offered separately as part number 270210-1, so be sure to order 270200-1 if you need the standard fixed-pin style). Installation is straightforward: the hinge base has mounting holes for two #10 flat head fasteners (fasteners are not included and must be purchased separately). Once installed, it provides a secure horizontal pivot point for Bimini top struts, canopy frames, and similar folding hardware where a 90 degree mounting angle is required. At approximately 0.21 pounds, it is a lightweight, low-profile fitting that will not add noticeable weight to a top assembly. Sea-Dog Line has manufactured marine hardware since 1933, and this deck hinge reflects that long history of boat deck hardware production.
