Round Stainless Flush Lock Ø45 mm – Marine Hatch Latching Mechanism with Pull Ring

The round inox lock Ø45 mm provides an elegant solution for securing hatches and lids on your boat. With its small diameter and low-profile design, it can be installed almost anywhere – from deck inspection ports for tanks, to covers of dry storage compartments or cabinet doors in the cabin. Once installed, the top of the latch is a smooth circular plate with an integrated ring. To open the hatch, simply lift the ring handle – it pops up from its recess to give you a firm grip. When closing, the ring pushes back down flush, remaining level with the surrounding surface.

This latch is constructed from cast AISI 316 stainless material, making it extremely corrosion-resistant and ideal for permanent outdoor use. Its polished finish matches other marine hardware, giving a professional look to your boat fittings. An included seal (O-ring or gasket) sits under the flange of the latch. This ensures that when the latch is closed, water is kept out of the opening – crucial for compartments that need to stay dry.

Applications and advantages:

• Wide Range of Use: This Ø45 mm latch is very versatile – its diameter fits many standard inspection holes. Use it for tank access caps (fuel or water), small bilge pump hatches, gear lockers, or even to replace factory latches on sailboat deck plates.
• Compact and Unobtrusive: Thanks to its small size, the latch doesn’t overwhelm the surface or snag feet and lines. This is particularly useful on small decks or tight spaces where every inch counts.
• Easy Operation: The mechanism is keyless – opening takes seconds with no key to fumble. Just pull up the built-in ring and lift. That makes it convenient for compartments you access frequently (e.g., day lockers for fishing tackle or tools).
• Secure Closure: Despite lacking a keyed lock, the mechanism features a spring catch or detent that prevents the cover from popping open on its own. When you close it, you’ll hear and feel a firm “click,” indicating the hatch is secured.
• Durability: The solid stainless steel body can withstand impacts and load. You can step on it on deck without worry – it’s built to handle pressure without bending or breaking. With no plastic parts in the working mechanism, there are no brittle components that might fail over time.
