National Marker N342493 Heavy Strap Hinge 8 in Stainless Steel

Product Description

The NATIONAL MARKER N342493 is an 8-inch heavy strap hinge constructed from stainless steel and designed for applications that require a wide mounting footprint. The tight pin configuration supports both right-hand and left-hand installations without modification. A patented bearing design eliminates metal-to-metal contact, producing smooth, quiet swing cycles. The stainless steel construction is rust-resistant and ACQ-safe, making it suitable for use with treated lumber, cedar, redwood, and other premium wood species. This hinge meets ANSI/BHMA A156.20 bearing grade cycle requirements, rated to 100,000 cycles. It is sold individually, one hinge per pack.

This heavy strap hinge is suited for residential and light commercial gate, door, and shutter applications where a wide mounting surface is present. The ACQ-safe rating makes it a practical choice for exterior installations involving pressure-treated wood, where standard zinc or low-grade steel hardware can corrode or react with the preservative chemistry in the wood. The reversible pin design reduces the need to stock separate left-hand and right-hand units on the job.

Installation Notes

Installation is typically performed by a carpenter, general contractor, or experienced DIYer using standard hand tools. Power down any gate operators or automated door systems before servicing hinges. Ensure the mounting surface is structurally sound and fastener holes are correctly piloted to prevent wood splitting. Follow local building codes and manufacturer fastener recommendations for load-bearing exterior applications.
