3pcs Marine Grade Self Closing Hinges | Self Closing | 5x5 | 7ft | 260 lbs | 1 3/4" - 2 1/4" Thick | SS316 | K51M-500D-A3-316

Oceanfront doors face the worst of it: salt, humidity, and constant weather that eats regular steel alive.

Waterson 316 marine grade stainless steel is made for exactly that exposure, carrying a 260 lbs, 7ft exterior door and closing it on its own so it never sits open to the elements. Three hinges keep the swing light despite the weight, and Waterson tucks the self closing action inside, safe from the sea air. Satin, black, brass, bronze, fast ship. 10-year warranty.
