National Mfg N342-766 Zinc Hd Spring Gate Hinge 3.5in 3-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N342-766 is a heavy-duty spring gate hinge built for automatic gate closure in residential and light commercial fence installations. Constructed from zinc for corrosion resistance, this hinge features a patented bearing design that eliminates metal-to-metal contact, resulting in smooth and quiet operation over repeated cycles. The integrated spring mechanism automatically closes gates weighing up to 50 pounds. A patented ratchet adjustment system allows tension to be dialed in without removing the hinge from the post, saving time during installation and field adjustment. This package contains 3 hinges.

This hinge is suited for wooden or metal gate installations where self-closing function is required, such as pool enclosures, yard gates, and fence line entries. The ratchet tension adjustment makes it practical for gates that see variable wind load or frequent traffic. Installers working on pool fence compliance applications will find the automatic-close feature relevant to safety code requirements. The zinc construction holds up in outdoor environments where bare steel would corrode.

Installation Notes

Installation is typically performed by fence contractors or general tradespeople using standard hand tools. Before adjusting spring tension, ensure the gate is fully hung and plumb. Use the ratchet adjustment mechanism to set closing force appropriate to the gate weight — do not exceed the 50-pound gate weight rating. Follow all applicable local fence and pool barrier codes when installing self-closing gate hardware.
