National Mfg N342-618 Zinc Sag Compensating Gate Latch

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N342-618 is a zinc sag-compensating gate latch designed for residential and light commercial fence applications. Its floating bar mechanism adjusts to compensate for more than 0.5 inches of gate sag, keeping the latch aligned and functional even as a gate shifts over time. The latch can be padlocked for added security. Fence installers, contractors, and property maintenance professionals typically install this hardware as part of new gate builds or replacement projects where sag has rendered an existing latch inoperable.

This latch suits wood, vinyl, and metal gate installations where moderate to significant gate sag is present or anticipated. The ambidextrous design supports both right-hand and left-hand gate configurations without requiring separate hardware. It ships as a carded retail-style package in a quantity of three units per pack, making it practical for multi-gate jobs or stocking service vehicles.

Installation Notes

Installation is typically performed by fence contractors or general maintenance trades using basic hand tools. Ensure the gate is fully hung and any underlying structural issues are addressed before mounting the latch. Follow the manufacturer's alignment instructions to properly set the floating bar adjustment for the specific amount of sag present. When padlocking, use a padlock shackle diameter compatible with the latch hasp opening.
