National Marker N348284 Stainless Steel Door Barrel Bolt

Product Description

The NATIONAL MARKER N348284 is a 4-inch stainless steel door barrel bolt designed for surface-mounted sliding-bolt security on doors, chests, and cabinets. The stainless steel construction provides strong resistance to corrosion, making it suitable for both interior and exterior applications where moisture or harsh conditions are a concern. It fits right-hand or left-hand door configurations without modification. Installers in facilities maintenance, commercial construction, and light industrial settings regularly spec this type of hardware for quick, reliable manual latching.

This barrel bolt is suited for a wide range of door and enclosure security applications in residential, commercial, and light industrial environments. Common install scenarios include utility room doors, storage cabinet doors, chest lids, and gate panels. Its ambidextrous mounting design reduces SKU complexity when specifying hardware for mixed-hand openings across a facility or job site.

Key Features

• 4-inch bolt length provides solid throw depth for positive door retention
• Stainless steel construction resists corrosion in damp or outdoor-adjacent environments
• Compatible with right-hand and left-hand door applications

Compatibility

Designed as a surface-mount barrel bolt replacement or new-installation hardware for standard doors, cabinet panels, and chest lids in residential and commercial applications.

Installation Notes

Installation is typically performed by a facilities technician, carpenter, or general contractor using basic hand tools. Secure all mounting screws fully into solid substrate or backing material to ensure the bolt operates under load without pull-out. Verify door alignment before final fastening so the bolt throw engages the strike cleanly. No special trade licensing is required, but follow applicable building codes for door hardware in commercial occupancies.
