National Mfg N151-522 3 Inch Black Barrel Bolt

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N151-522 is a 3-inch black barrel bolt designed to provide basic security latching on lightweight interior doors, storage chests, cabinets, and similar enclosures. The bolt slides into a strike case to hold a door or panel in a closed, locked position. When mounted vertically, a notch in the case retains the bolt automatically, preventing unintended opening. This hardware is straightforward to install and requires only common hand tools. It is sold in a package of 10 units, making it practical for contractors, maintenance technicians, and facilities personnel handling multiple installations at once.

This barrel bolt is suited for light-duty security applications in residential and commercial settings. Typical uses include cabinet shops, facility maintenance, light carpentry, and property management work where a simple, reliable surface-mounted latch is needed on interior doors, box lids, or panel enclosures. The design accommodates both right-hand and left-hand door swings, eliminating the need to stock separate handed hardware for mixed installations.

Installation Notes

Installation is typically performed by carpenters, maintenance technicians, or general contractors using standard hand tools. Mount the bolt body and strike case to a clean, flat surface with appropriate fasteners for the substrate material. Ensure the bolt and strike are aligned before final fastening to allow smooth operation. No power should be required to the surrounding assembly, but confirm any associated electrical enclosures are de-energized before working in close proximity.
