National Marker N151589 Door Barrel Bolt 3 Inch

Product Description

The NATIONAL MARKER N151589 is a 3-inch barrel bolt designed for security latching on lightweight doors, chests, cabinets, and similar enclosures. The bolt body is constructed of steel with a brass bolt and brass knob. The sliding bolt mechanism provides a simple, tool-free latch that locks the door or panel in place when engaged. This hardware is suited for both residential and light commercial applications where a low-profile, surface-mounted latch is needed. Installation is straightforward and is typically handled by a general contractor, carpenter, or facilities maintenance technician.

This bolt is appropriate for use on lightweight interior doors, storage chests, cabinet doors, and utility enclosures. It is designed to work on both right-hand and left-hand applications, providing flexibility during installation. When mounted vertically, the notch-in case holds the bolt in the locked position without additional hardware. This makes it a practical choice for overhead cabinet latches, vertical panel closures, and similar use cases where gravity-assisted locking is beneficial.

• Steel body construction with brass bolt and brass knob
• Right-hand and left-hand compatible for installation flexibility

Installation Notes

Installation requires only basic hand tools including a drill and screwdriver. Mount the bolt body to the door face and align the strike plate to the door frame or adjacent panel before fastening. No power should be required to be shut off for this hardware installation, but ensure the door or panel is fully closed and aligned before marking hole locations. Follow applicable building codes for security hardware in commercial settings.
