The body is hex shaped, making it easy to grip with a wrench for precise tension adjustments. It is manufactured from aluminum with a zinc finish for corrosion resistance, while the eyes are constructed from steel for added strength at the load-bearing connection points. This turnbuckle suits contractors, riggers, and maintenance professionals who need a reliable adjustable tensioning device for light to medium load applications.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle is appropriate for residential and commercial rigging setups, wire rope tensioning, fencing, antenna guy wire systems, and general structural bracing work. The eye-and-eye configuration allows attachment to hooks, shackles, eyebolts, or wire rope thimbles at both ends. It follows the catalog 2170BC series designation from National Marker and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEye-and-eye configuration for versatile attachment at both ends\u003c\/li\u003e\n  \u003cli\u003eHex shaped body allows wrench engagement for controlled tensioning\u003c\/li\u003e\n  \u003cli\u003eAluminum body with zinc finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSteel eyes deliver strength at load-bearing connection points\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch thread diameter with 16 inch take-up length\u003c\/li\u003e\n  \u003cli\u003eLightweight design at 0.463 pounds per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use turnbuckle fitting standard 3\/8 inch rigging hardware configurations in residential and commercial tensioning applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTurnbuckles of this type are installed by qualified riggers or contractors following applicable load-rating and rigging safety standards. Always verify that the working load limit of the turnbuckle matches or exceeds the intended load before tensioning. Use a wrench on the hex body to adjust tension evenly, and secure the turnbuckle body with a locking wire or jam nut where vibration or cyclic loading is present. Inspect eyes and threads for wear or deformation before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTake-Up Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Eye and Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEye Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.463 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613124837\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCatalog Series\u003c\/strong\u003e: 2170BC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51346623365426,"sku":"N221770","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550412.jpg?v=1782085751","url":"https:\/\/voomisupply.com\/products\/national-marker-n221770-eye-eye-turnbuckle-3-8x16-in-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
