Not every hatch needs a key — but the ones that do need one that works every time. The 316 Stainless Steel Marine Floor Lock combines a smooth turning latch mechanism with a keyed cylinder lock, giving you two layers of access control for deck plates, cabin hatches, and below-deck compartments. Flush-mounted and polished, it disappears into the deck when closed and opens with a quarter-turn when you need it.
Two Layers of Security, One Compact Fitting
The turning latch keeps the hatch firmly closed against wave action and pressure. The key lock adds a second barrier — useful for securing valuables, fuel compartments, or restricted areas aboard a vessel. Built from 316 stainless steel, it handles constant saltwater exposure without seizing, pitting, or losing its finish.
