Measuring 3\/16 inches in body diameter and 5-1\/2 inches in take-up length, it delivers a 45 pound load capacity suited for light-duty rigging, bracing, and support applications. The zinc construction provides basic corrosion resistance for general indoor and sheltered outdoor use. Contractors, maintenance technicians, and experienced DIYers install these as part of wire rope assemblies, cable bracing systems, and structural tie-back setups.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle is appropriate for residential and light commercial applications where a small-diameter, low-load tensioning device is required. Typical use cases include cable railing systems, fence wire tensioning, antenna guy wires, and general rigging tie-backs. It ships in bulk quantities of 10 units per package, making it suitable for projects requiring multiple adjustment points throughout a single installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEye-and-eye configuration allows connection to rings, hooks, and cable ends on both sides\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch body diameter with 5-1\/2 inch take-up length for compact tensioning adjustments\u003c\/li\u003e\n  \u003cli\u003e45 pound load capacity rated for light-duty rigging and support work\u003c\/li\u003e\n  \u003cli\u003eZinc construction offers corrosion resistance for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eBulk pack of 10 units per package for multi-point installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose light-duty eye-and-eye turnbuckle compatible with standard 3\/16 inch wire rope, cable, and rigging hardware assemblies requiring a compact tensioning component.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by contractors, riggers, or maintenance technicians familiar with basic rigging hardware. Ensure all connected hardware — hooks, thimbles, and cable ends — is rated at or above the 45 pound load capacity of this turnbuckle before tensioning. Thread both eye ends evenly to maintain balanced tension and prevent side-loading the frame. Do not exceed the rated load capacity; overloading zinc turnbuckles can cause sudden failure without visible warning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTake-Up Length\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Fittings\u003c\/strong\u003e: Eye and Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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 MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221-721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51559017644338,"sku":"N221-721","price":27.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/036a2c80f97bd487e3458b95350ffb90.jpg?v=1786425859","url":"https:\/\/voomisupply.com\/products\/national-mfg-n221-721-eye-eye-turnbuckle-3-16x5-1-2-45lb-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
