National Marker N221861 Hook Eye Turnbuckle Zinc

Product Description

The NATIONAL MARKER N221861 is a hook and eye turnbuckle designed for tensioning and adjusting tension in wire rope, cable, and rod assemblies. The body measures 0.25 inches in take-up diameter and 7.5 inches in length, with a hex-shaped profile that allows for wrench adjustment. The body is manufactured from aluminum with a zinc finish, while the hook and eye hardware are steel. At 0.108 pounds, this is a lightweight tensioning fastener suited for light-duty rigging, bracing, and support applications. Licensed tradespeople and rigging professionals install this type of hardware in structural, mechanical, and general utility settings.

This turnbuckle is appropriate for residential and light commercial applications where cable or rod tension adjustment is required. Typical uses include fence bracing, antenna guy-wire tensioning, structural tie-back assemblies, and similar rigging scenarios. The hex body allows for standard wrench engagement during tensioning without requiring a special tool. Sold individually, with a minimum order quantity of 10 units, making it practical for stocking by contractors who install cable bracing or tensioning systems regularly.

Installation Notes

Turnbuckles of this type are installed by contractors, riggers, or general tradespeople working on cable bracing, antenna support, or structural tie-back systems. Before installation, ensure all connected hardware and anchor points are rated for the intended load. Use the hex body with an appropriate wrench to achieve the desired tension, and always install safety tie wire or locking nuts where vibration or dynamic loading is present.
