National Mfg N342-774 Spring Gate Hinge 3.5in Black 3 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N342-774 is a heavy-duty spring gate hinge engineered for automatic gate closure in residential and light commercial fence installations. Built to handle gates weighing up to 50 pounds, this hinge uses a patented bearing design that eliminates metal-to-metal contact, reducing wear and producing smooth, quiet operation over the service life of the hardware. The patented ratchet adjustment mechanism allows field technicians and installers to dial in spring tension without removing the hinge from the gate. Sold as a pack of three, this hinge is finished in black for a clean, consistent appearance on painted or powder-coated fence systems.

This hinge is suited for wood, vinyl, or metal gate frames where self-closing function is required. Typical installations include residential backyard gates, pool enclosure gates, and light commercial fence access points. The spring-loaded design is commonly specified where code or safety guidelines require gates to self-close, such as pool barrier installations. The black finish blends with standard ornamental and tubular steel fence systems. Installation is handled by general contractors, fence installers, and experienced DIYers with basic hand tools.

Installation Notes

Installation is typically performed by fence installers or general contractors using standard hand tools including a drill, screwdriver, and level. Verify gate weight does not exceed the 50-pound rated capacity before installation. Adjust spring tension using the ratchet mechanism after mounting to achieve consistent self-closing action. Follow all local building and pool barrier codes that may specify self-closing hardware requirements.
