3pcs Marine Grade Self Closing Hinges | Soft Closing | 5x5 | 7ft | 260 lbs | 1 3/4" - 2 1/4" Thick | SS316 | K51M-500D-B3-316

Coastal storms and gusty patios turn a heavy exterior door into a slamming hazard, and salt air corrodes whatever tries to control it. 

Waterson 316 marine grade stainless steel holds up to that seaside abuse while easing a 260 lbs, 7ft door into a soft, controlled close, even when the wind is up. The soft close hides inside the hinge, so nothing exposed to the ocean spray wears out early. Satin, black, brass, bronze, fast ship. 3-year warranty.
