Built from stainless steel with an aluminum body, this turnbuckle resists atmospheric corrosion and is nonmagnetic, making it well suited for marine environments and exposed outdoor installations. The hex-shaped body allows adjustment by hand or with a standard wrench. At 3\/16 inches by 5-1\/2 inches, it fits into light- to medium-duty tensioning applications. The eyes are passivated to provide an additional layer of corrosion resistance beyond the base stainless steel construction. Installers working in coastal, poolside, or other high-moisture environments will find this hardware ready for long-term exposure.\u003c\/p\u003e\u003cp\u003eThis turnbuckle is appropriate for marine rigging, fence tensioning, cable rail systems, and general outdoor line management where corrosion resistance and nonmagnetic properties are required. It is sold individually and is packaged loose. The passivated eye fittings make it a reliable choice for applications where galvanic corrosion from dissimilar metals is a concern, particularly in saltwater-adjacent environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction with aluminum body for corrosion resistance in marine and outdoor settings\u003c\/li\u003e\n\u003cli\u003eNonmagnetic material suitable for sensitive or specialized installation environments\u003c\/li\u003e\n\u003cli\u003ePassivated eyes for superior resistance to atmospheric and surface corrosion\u003c\/li\u003e\n\u003cli\u003eHex-shaped body enables adjustment by hand or with a standard wrench\u003c\/li\u003e\n\u003cli\u003e3\/16 inches by 5-1\/2 inches sizing fits light- to medium-duty cable and line tensioning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hook eye turnbuckle for marine rigging, outdoor cable assemblies, and tensioning applications requiring corrosion-resistant, nonmagnetic hardware.

Ensure all connected lines and anchor points are rated for the intended load before tensioning. Use the hex body with an appropriate wrench to achieve final tension without overloading the fitting. Inspect the passivated eye surfaces periodically in high-salt or high-humidity environments to confirm the protective finish remains intact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless steel with aluminum body\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEye Finish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Properties\u003c\/strong\u003e: Nonmagnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.067 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613191341\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: N221945\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51343288500530,"sku":"N221945","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550436.jpg?v=1782019843","url":"https:\/\/voomisupply.com\/products\/national-marker-n221945-hook-eye-turnbuckle-3-16x5-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
