Sea-Dog Line Side Mount Deck Hinges
Sea-Dog Line Side Mount Deck Hinges: Built for the Open Water
When it comes to securing a Bimini top or canvas enclosure on your boat, the hardware holding it all together matters as much as the fabric itself. Sea-Dog Line has been engineering marine hardware since the early 1920s, and their side mount deck hinges reflect nearly a century of understanding what boats — and boaters — demand from deck fittings.
What Are Side Mount Deck Hinges?
Side mount deck hinges are vertically mounted fittings designed to attach the eye end of a Bimini top or similar canvas frame directly to the deck or gunwale of a boat. Unlike flat-mount hinges, the side-mount design allows the fitting to pivot the Bimini frame up or down while keeping a secure, low-profile connection to the boat's structure. Choosing the right material and pin size for your application is key to long-term reliability in a saltwater or freshwater environment.
Sea-Dog Line's Side Mount Deck Hinge Lineup
Sea-Dog Line offers side mount deck hinges in two primary material families, giving boaters the flexibility to choose the right balance of weight, cost, and corrosion resistance for their vessel.
- UV-Resistant Injection Molded Nylon: Sea-Dog's nylon side mount deck hinges are constructed of UV-resistant injection molded nylon and are available in black, white, and grey colorways — making it easy to match existing hardware or canvas color schemes. These feature a 1/4" pin size, a 2-hole base measuring 2-7/16" x 7/8", and install with standard #10 FH fasteners. Their lightweight construction and resistance to UV degradation make them a popular choice for recreational boaters seeking a cost-effective, durable solution.
- 316 Stainless Steel: For boaters who need maximum corrosion resistance — especially in saltwater applications — Sea-Dog offers side mount deck hinges constructed of investment cast 316 stainless steel. Available in 1/4" and 5/16" pin sizes (models 270250 and 270255), the stainless versions deliver a polished, professional look alongside the strength and marine-grade durability that 316 SS is known for. A heavy-duty four-hole version is also available with a 5/16" pin size, measuring 1-7/8" x 2-13/16", and installs with 1/4" FH fasteners.
