Sea-Dog Heavy Duty Barrel Bolt 221243-1, 3-3/4 Inch, 316 Stainless Steel

The Sea-Dog Heavy Duty Barrel Bolt, part number 221243-1, is a surface-mounted slide bolt built for securing doors, gates, and cabinets aboard boats and in other corrosive environments. It is investment cast from 316 stainless steel, a grade chosen for its resistance to saltwater and marine air corrosion, giving the bolt long-term durability in exposed applications. This barrel bolt can serve as either a primary locking mechanism or as a back-up lock alongside another latch, and it is versatile enough for vertical, horizontal, left-hand, or right-hand mounting. When installed vertically, a notch machined into the barrel holds the bolt securely in the locked position, preventing it from sliding open on its own. The bolt measures 3-3/4 inches long, 1-1/2 inches wide, and 5/8 inch high, making it a compact fit for smaller doors, hatches, and cabinet faces where a heavier-duty bolt than a standard cabinet latch is needed. It surface mounts using #8 flat head fasteners, which are not included and must be sourced separately to match the mounting surface. The part is sold individually with a standard pack quantity of 5 each for buyers outfitting multiple doors or cabinets. Its stainless steel construction and simple slide mechanism make it easy to install and operate without special tools.
