National Mfg N151-449 Barrel Bolt 2.5 Inches Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N151-449 is a zinc barrel bolt designed for sliding door and gate latching applications. The barrel bolt provides a simple, manually operated slide-latch mechanism that engages a strike plate or loop to secure doors, gates, or panels in the closed or open position. At 2.5 inches in length, it suits light-duty to medium-duty applications. Mounting hardware is included, so no separate fastener sourcing is required. This type of hardware is typically installed by general contractors, finish carpenters, or experienced tradespeople working on utility enclosures, access panels, and outbuildings.

This barrel bolt is suited for interior and exterior installations where a straightforward slide-latch is required. Common applications include shed doors, fence gates, utility room doors, equipment enclosure panels, and secondary door security. The zinc construction provides corrosion resistance suitable for covered or semi-exposed environments. It is sold in a package of 10 units, making it practical for multi-door projects or stocking purposes.

Installation Notes

Barrel bolts are typically installed by carpenters or general tradespeople using basic hand tools including a drill and screwdriver. Align the bolt body and strike loop carefully before fastening to ensure smooth slide action. For exterior applications, confirm the mounting surface is adequately sealed to prevent moisture intrusion behind the hardware. No special trade licensing is required, but installations on fire-rated or code-regulated door assemblies should be verified against applicable building codes.
