National Mfg N151-878 Galvanized Barrel Bolt 3 Inches

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N151-878 is a 3-inch galvanized barrel bolt designed for basic security applications on lightweight doors, chests, and cabinets. The bolt features a brass pin and a galvanized steel body that resists corrosion in typical indoor environments. A notch in the case holds the bolt in a locked position during vertical use, adding a passive retention feature that prevents accidental unlatching. The bolt diameter is 0.32 inches. Mounting screws are included. This hardware is suited for carpenters, general contractors, and property maintenance professionals who need a straightforward surface-mounted latching solution.

This barrel bolt is appropriate for residential and light commercial use on interior doors, storage chests, cabinet doors, gates, and similar lightweight enclosures. The design accommodates both right-hand and left-hand applications without modification, making it a versatile stock item for service vans and supply rooms. Vertical installation is the intended orientation when the locking notch feature is required to hold the bolt in place. The included screws allow for immediate installation without sourcing additional fasteners.
