National Mfg N222-018 Hook Hook Turnbuckle 5/16x9 Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-018 is a hook-and-hook turnbuckle designed for tightening or drawing together lines, cables, and rigging assemblies. The body is extruded aluminum with a hex profile, allowing adjustment by hand or with a standard wrench. Both end fittings are steel wire hooks with a zinc finish for corrosion resistance. At 5/16 inch body diameter and 9 inches in length, this turnbuckle suits medium-duty tensioning tasks across a range of trade and general contractor applications.

This turnbuckle is suited for residential and light commercial installations where cables, wire rope, or lines require tensioning or alignment. Typical applications include fence and gate bracing, overhead cable management, structural tie-back lines, and general rigging work. The zinc finish over steel hooks and extruded aluminum body makes it appropriate for indoor applications and sheltered outdoor environments. It ships bagged loose and is sold in packages of 10 units.

Installation Notes

Installation is typically performed by general contractors, riggers, or maintenance trades using standard hand tools. Ensure both hook ends are fully engaged and seated on their attachment points before applying tension. Do not exceed the rated load capacity of the turnbuckle or the connected cable and hardware. Inspect hooks and threads for deformation or wear before placing the assembly under load.
