3pcs 316 Stainless Steel Exterior Door Hinges | Soft Closing | 4x4 | 7ft | 260 lbs | 1 3/8" - 1 3/4" Thick | SS316 | K51M-400-B3-316

Pool code says the gate must close and latch on its own. Real life says sometimes you just need it to stay open while you carry things through. Salt air chips away at your ability to have both.

That is exactly the gap Waterson 316 marine grade stainless steel self closing hold open hinge fills. Its on-hinge hydraulic damper, tunable for tension and speed, delivers a dependable self close as the posts move over time, while a built in hold open feature lets you leave the gate parked open whenever you want. No closer sits outside the gate to catch the weather. 10-year warranty.
