AAA Stainless Steel Barrel Bolt – 316 is a practical sliding latch designed to secure doors, hatches, access panels, lockers, cupboards, cabinets, and storage compartments. Manufactured from stainless steel 316, this marine door latch is suitable for installations where hardware may be exposed to moisture, salt spray, changing weather, or regular use. Its straightforward sliding-bolt mechanism provides a convenient way to hold an opening securely in the closed position without requiring a complicated locking system.

The barrel bolt consists of a sliding cylindrical bolt, a main mounting plate, and a receiving keeper. To close the latch, the bolt slides into the keeper and retains the door, hatch, or panel. Pulling the operating knob back releases it for opening. The smooth manual action makes this stainless steel barrel bolt suitable for frequently accessed areas aboard boats, yachts, fishing vessels, leisure craft, and other marine installations. It can also be used for appropriate outdoor cabinets, utility enclosures, and general hardware applications where a compact surface-mounted barrel latch is required.

Two size variants are available to accommodate different installation spaces and hardware requirements. The first variant measures 76.2mm (L) × 30mm (W), offering a compact solution for smaller cabin doors, lockers, cupboards, and access panels. The second variant measures 92mm (L) × 38mm (W) and provides a larger mounting footprint for wider doors, hatches, cabinets, and storage compartments. Buyers should check the available mounting area, door orientation, keeper position, and required clearance before choosing a size. The two components must be aligned correctly so that the bolt can enter and leave the keeper without obstruction. The confirmed manufacturer models are 85026 for the 76.2mm version and 85027 for the 92mm × 38mm version.

Stainless steel 316 is commonly selected for marine hardware because it provides strong resistance to corrosion in wet and salt-containing environments. This makes the product a suitable alternative to ordinary interior door hardware when fitting boat cabins, deck lockers, storage areas, or exposed access points. Its surface-mounted design also allows the bolt and keeper to remain visible for straightforward operation and inspection. Although often described as a heavy duty barrel bolt or stainless steel boat latch, suitability for a particular installation depends on the door or hatch construction, mounting surface, fasteners, alignment, and expected load. It is a retaining latch rather than a keyed security lock, and installation fasteners should be selected separately according to the mounting material and application.
