Marina and oceanfront doors take relentless salt exposure, and a big one needs to close itself while still holding open on demand.

Waterson 316 marine grade stainless steel handles both on a heavy 8ft door, self closing and latching against the weather, then parking wide open when your arms are full of gear. Closer, spring, and hold open sit inside the marine grade hinge, sealed away from the coastal air that corrodes ordinary hardware. Satin, black, brass, bronze, fast ship. 10-year warranty.
