The NATIONAL MARKER N348946 is a stainless steel door barrel bolt designed for security and latching applications on doors, chests, cabinets, and similar enclosures. The bolt slides into a fixed keeper to hold a door or panel securely closed without a lock cylinder. Stainless steel construction provides strong resistance to corrosion, making this bolt suitable for humid or wet environments where standard steel hardware would degrade. At 2.5 inches, it fits standard residential and light commercial door and cabinet applications. Licensed trade professionals and skilled installers use barrel bolts like this for quick, reliable surface-mounted latching solutions.
This barrel bolt is appropriate for both residential and light commercial installations. Common applications include interior and exterior doors, storage chest lids, cabinet doors, gate panels, and utility enclosures. The design supports right-hand and left-hand mounting, so it can be positioned on either side of a door or panel without requiring a different part. It is sold individually and installs with standard fasteners.
Designed as an OEM-style replacement or new-install surface-mount barrel bolt for standard doors, cabinets, chests, and enclosures requiring a sliding latch.
Installation is typically performed with a screwdriver or drill and standard wood or sheet-metal screws appropriate to the substrate. Confirm the mounting surface is structurally sound and the keeper aligns cleanly with the bolt throw before final fastening. No specialized trade license is required, though installations on exterior doors in commercial occupancies may be subject to local building code review.
