Heavy-duty Marine-Grade Cast Butterfly Strap Hinge. Unlike perfectly square butt hinges, this configuration uses tapered trapezoidal leaves, which help spread out stress across structural fiberglass or wooden boat panels while maintaining a highly aesthetic look.
Key Visual Features of this Model
Protruding Pin Barrel: The barrel sticks upward above the face plates. This specific setup is engineered for surfaces that do not sit completely flat against each other, allowing doors or lids to clear outer trim molding smoothly.
6-Hole Countersunk Mount: With three screw locations on each side, this distributes extreme heavy weight or high structural pulling forces far better than a simple 4-hole pattern.
Thick-Walled Investment Casting: You can notice the thick, smooth edges along the outer perimeter. This part is molded from cast 316 stainless steel (approx. 4mm to 5mm thick) to prevent cracking under physical impacts or boat pounding.
