National Mfg N160-754 Zinc Hook Jamb Latch 4 Inches

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N160-754 is a 4-inch zinc hook jamb latch engineered for heavy-duty door and gate retention in demanding environments. This cam-action latch holds wood and metal doors firmly against the door jamb, providing reliable closure without the need for padlocks or secondary hardware in everyday service. The reversible strike plate accommodates door frames ranging from 1-1/2 inches to 3-1/2 inches thick, making it adaptable across a wide range of construction styles. Zinc construction resists corrosion in outdoor and agricultural settings. Sold in a package quantity of 20 units.

This latch is designed for farm and utility buildings where wood or metal doors require secure, positive retention against the jamb. It is also well suited for end gates on stake trucks and similar trailer applications. The cam-action mechanism allows fast, single-motion engagement and release, which is practical in high-traffic service environments. Pre-punched mounting holes simplify installation on standard door and gate framing. The latch supports both right-hand and left-hand door configurations without requiring separate hardware.
