Sea-Dog Barrel Bolt - Chrome Finish - 2-1/2"

The Sea-Dog Barrel Bolt Chrome Finish 2-1/2" is a heavy-duty surface-mounted locking mechanism built from chrome-plated extruded brass. This hardware-grade barrel bolt delivers dependable security for doors, gates, equipment cabinets, and storage enclosures commonly found in tactical facilities, armories, and field operations. Its versatile orientation capability—vertical, horizontal, left, or right-hand configuration—makes it a go-to choice when primary locking systems require redundant backup security or when a single-point failsafe is needed across multiple access points.

The 2-1/2" bolt length provides practical reach for most door and gate frames without excessive protrusion. Chrome plating resists corrosion in outdoor and high-moisture environments—critical where salt air, humidity, or frequent washdowns would degrade standard steel hardware. In vertical mounting, the barrel's integral notch holds the bolt in locked position, requiring intentional manipulation to disengage. Installation uses six #6 flathead fasteners (sold separately), allowing flush mounting without protruding hardware that could snag gear or create a tactical liability. The compact footprint—roughly 4 inches overall length—fits tight spaces where bulkier deadbolt or slide-bolt mechanisms prove impractical.

This barrel bolt serves operators, facility managers, and equipment custodians who need rapid, tool-free access control without electronic dependencies. Whether securing an armory door, locking an equipment locker on a forward operating base, or providing backup security on a gate that sees frequent tactical movement, the Sea-Dog 222502-1 delivers straightforward mechanical reliability. The design's simplicity—no springs, catches, or complex internal mechanisms—ensures function in extreme temperature swings and after extended field storage. Brass construction avoids magnetic interference concerns relevant to certain tactical applications.

Barrel bolts remain the industry standard for secondary locking systems precisely because they function identically whether mounted vertically or horizontally, require no special tools to operate, and degrade gracefully under impact rather than failing catastrophically. At TacticalSurplusUSA, we stock Sea-Dog hardware because its track record across marine, industrial, and tactical venues confirms performance under real-world conditions. This 2-1/2" model balances reach, compactness, and corrosion resistance for mid-range security applications where traditional slide bolts or pin latches fall short.
