National Marker N151878 Galvanized Steel Door Barrel Bolt

Product Description

The NATIONAL MARKER N151878 is a 3-inch galvanized steel door barrel bolt designed for security and latching applications on lightweight doors, chests, cabinets, and similar enclosures. The bolt body is constructed of galvanized steel, while the bolt itself and the knob are made of brass, providing corrosion resistance suited for general interior use. The bolt diameter measures 0.32 inches. This type of hardware is typically installed by maintenance technicians, carpenters, or general contractors as part of door and cabinet security work.

This barrel bolt is suited for residential and light commercial applications where a simple slide-bolt latch is needed. It supports both right-hand and left-hand mounting configurations, making it adaptable to a variety of door swing orientations. When mounted vertically, the notch-in case design holds the bolt in the locked position without additional hardware, adding a layer of passive security. Typical applications include interior doors, utility room cabinets, storage chests, and access panels.
