The hex-shaped body is manufactured from aluminum with a zinc finish, while the eyes are steel for added strength at the connection points. This turnbuckle is a standard hardware component used by riggers, contractors, and trade professionals in structural, marine, and general tensioning applications. The aluminum body keeps weight low without sacrificing dimensional integrity, and the zinc finish provides a basic level of corrosion resistance for typical indoor and light outdoor use.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle fits into applications where a compact, adjustable tensioning device is required between two eye-terminated connections. Common uses include tensioning fence wire, guy wires, safety cables, and structural bracing in both residential and light commercial settings. The eye-and-eye configuration allows attachment to hooks, shackles, or fixed anchor points. It is sold individually and is suited for installations where moderate load tensioning is needed at a 5\/16-inch thread size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEye and eye configuration for direct connection to anchor points or rigging hardware\u003c\/li\u003e\n  \u003cli\u003eHex-shaped aluminum body for wrench engagement during tensioning\u003c\/li\u003e\n  \u003cli\u003eZinc finish on body provides corrosion resistance for light outdoor use\u003c\/li\u003e\n  \u003cli\u003eSteel eyes for strength at the load-bearing connection points\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch thread diameter with 9-inch take-up length\u003c\/li\u003e\n  \u003cli\u003eLightweight aluminum construction reduces overall assembly weight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard eye-and-eye turnbuckle replacement or new-installation component for 5\/16-inch tensioning assemblies.

Before tensioning, ensure all connected hardware is rated for the intended load and that anchor points are secure. Do not over-torque the turnbuckle body, as aluminum threads can be damaged by excessive force. Inspect eyes and connecting hardware for proper seating before applying full tension.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTake-Up Length\u003c\/strong\u003e: 9 inches\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\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEye Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Eye and Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.204 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613124929\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: N221754\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51346208948530,"sku":"N221754","price":43.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550414.jpg?v=1782073969","url":"https:\/\/voomisupply.com\/products\/national-marker-n221754-eye-eye-turnbuckle-5-16-in-x-9-in","provider":"Voomi Supply","version":"1.0","type":"link"}
