National Marker N342485 Heavy Strap Hinge 6 in Stainless Steel

Product Description

The NATIONAL MARKER N342485 is a 6-inch heavy strap hinge constructed from stainless steel and intended for applications where wide mounting surfaces require a durable, corrosion-resistant pivot point. The patented bearing design eliminates metal-to-metal contact, producing smooth and quiet operation over extended service life. The hinge meets ANSI/BHMA A156.20 bearing grade cycle requirements, rated for 100,000 cycles. A tight pin configuration supports both right-hand and left-hand installation without modification. This hinge is sold individually and is suited for installation by carpenters, general contractors, and maintenance tradespeople working on gates, doors, and heavy-duty cabinetry.

The N342485 is rated as ACQ safe, making it appropriate for use with pressure-treated lumber as well as naturally resistant woods such as cedar and redwood. The rust-resistant stainless steel construction suits both interior and exterior applications where moisture exposure or corrosive environments are a concern. Typical installations include barn doors, heavy exterior gates, storage enclosures, and utility panel covers where standard hinges lack sufficient load-bearing width or corrosion resistance.

Key Features

• Stainless steel construction provides rust resistance for interior and exterior use
• ACQ safe rating allows direct contact with pressure-treated, cedar, and redwood lumber
• Patented bearing design eliminates metal-to-metal contact for smooth, quiet operation
• Meets ANSI/BHMA A156.20 bearing grade cycle requirements at 100,000 cycles
• Tight pin design supports right-hand or left-hand installation
• Wide strap profile suited for applications with broad mounting surfaces

Compatibility

Designed as an OEM-style replacement or new-installation heavy strap hinge for gates, exterior doors, and heavy-duty panels requiring a wide mounting surface and corrosion-resistant hardware.

Installation Notes

Installation is typically performed by carpenters, general contractors, or skilled maintenance personnel using standard hand tools. Power down or de-energize any associated automated gate or door operator before beginning work. Fastener selection should be appropriate for the substrate material and exposure conditions; use stainless steel fasteners to maintain the corrosion-resistance rating of the assembly. Follow applicable building codes and manufacturer load guidelines when determining hinge quantity per door or gate leaf.
