National Mfg N223-040 Zinc Quick Link 3/8 in 10 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N223-040 is a 3/8-inch zinc quick link designed for fast, reliable connections between two lengths of chain or for attaching accessories to an existing chain run. The zinc construction provides corrosion resistance suitable for general-purpose fastening applications. Each unit ships in a box of 10 loose links, making it practical for contractors and service techs who need multiple connection points on a single job. These links do not require a locking mechanism, allowing quick installation and reconfiguration without additional hardware.

The N223-040 is used wherever a temporary or semi-permanent chain connection is needed without the complexity of a shackle or clevis pin. Typical applications include hanging equipment, securing chain runs in mechanical rooms, HVAC unit tie-downs, and general trade use in plumbing, electrical, and facilities maintenance. The 3/8-inch size suits mid-range chain diameters common in commercial and residential service work. The 10-piece package quantity supports multi-point installations or standard stock replenishment for service vehicles and supply rooms.
