Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N121-715 is a heavy-duty open S hook designed for hanging, connecting, and organizing loads in a wide range of trade and industrial applications. Constructed from zinc plated steel, this S hook measures 2.5 inches in length and supports loads up to 140 pounds. The open design allows for fast, tool-free installation onto hooks, rods, chains, or wire shelving. Its zinc plating provides corrosion resistance in typical indoor service environments. This hardware is commonly installed by HVAC technicians, plumbers, electricians, and general contractors for securing components, hanging equipment, or routing materials.

The N121-715 is suited for residential and light commercial applications where a reliable, load-rated hanging point is needed. Common uses include supporting conduit, pipe, ductwork accessories, tools, and storage organization systems. The open S configuration makes it easy to attach and reposition without disassembly. Each package contains 10 hooks, making it practical for multi-point installations or keeping spares on hand.
