The body is hex-shaped for wrench engagement, allowing precise tension adjustment without slipping. The aluminum body carries a zinc finish for corrosion resistance, while the hook and eye ends are steel for load-bearing strength. At 0.32 pounds, it is lightweight enough for overhead and vertical installations where cumulative load matters. This turnbuckle suits contractors, riggers, and maintenance trades who need a reliable, adjustable tensioning device on the job.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle is appropriate for residential and light commercial use, including fence wire tensioning, awning and shade structure rigging, cable railing systems, sign hanging, and general tensioning tasks where a 3\/8 inch thread size and 10-1\/2 inch take-up length are specified. The hook end allows quick attachment to rings, eyes, and anchor points without threading, while the eye end accepts bolts and pins. It is sold individually and is a catalog 2172BC series part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHex-shaped aluminum body allows standard wrench engagement for precise tension adjustment\u003c\/li\u003e\n  \u003cli\u003eZinc finish on aluminum body provides corrosion resistance for indoor and protected outdoor use\u003c\/li\u003e\n  \u003cli\u003eSteel hook and eye ends deliver load-bearing strength at connection points\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch thread size and 10-1\/2 inch length suit a wide range of light structural tensioning applications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.32 pounds, suitable where cumulative assembly weight is a factor\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, MOQ of 1\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 for applications requiring a 3\/8 inch hook-and-eye turnbuckle with a hex body.

Always de-tension the assembly and relieve load before removing or replacing a turnbuckle. Thread both the hook and eye ends evenly to maintain alignment and avoid cross-threading. Do not exceed the rated working load limit for the application; consult applicable structural or rigging codes for load requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Fittings\u003c\/strong\u003e: Hook 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\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook and Eye Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCatalog Series\u003c\/strong\u003e: 2172BC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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 HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221-887\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STANLEY","offers":[{"title":"Default Title","offer_id":51699703546162,"sku":"N221-887","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccab406b71172dee2b668944733161e7.jpg?v=1788379517","url":"https:\/\/voomisupply.com\/products\/national-hardware-n221-887-turnbuckle-hook-eye-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
