National Hardware N221-846 Turnbuckle Hook Eye 3/16 in

Product Description

The NATIONAL HARDWARE N221-846 is a hook-and-eye turnbuckle designed for tensioning wire rope, cable, and rod assemblies in light-duty structural and rigging applications. The body measures 5-1/2 inches in length with a 3/16 inch take-up size and features a hex-shaped profile for wrench engagement during adjustment. The frame is manufactured from aluminum with a zinc finish for corrosion resistance, while the hook and eye ends are steel for load-bearing strength. This turnbuckle suits contractors, riggers, and general tradespeople working on cable runs, fencing, bracing, and tensioning tasks.

This turnbuckle is suited for residential and light commercial applications where cable or wire assemblies require periodic tension adjustment. Common install scenarios include fence bracing, awning frames, cable railings, and support wire tensioning. The hex body allows standard wrench access for precise take-up without requiring specialized tooling. It ships as an individual unit and is stocked for single-piece or multi-piece procurement.

Installation Notes

Installation is typically performed by general contractors, riggers, or maintenance tradespeople using standard open-end or adjustable wrenches on the hex body. Ensure the hook and eye ends are fully engaged and safety-clipped or moused where required by the applicable building or rigging code before applying load. Do not exceed the rated working load for the 3/16 inch size class. Inspect threads for damage before tensioning and verify that mating hardware is compatible in both material and diameter.
