Built from stainless steel with an aluminum hex-shaped body, this turnbuckle delivers strong corrosion resistance in demanding environments. The hex body allows adjustment by hand or with a standard wrench, making field use straightforward. Eyes are passivated for superior corrosion resistance, and the assembly is nonmagnetic throughout. At 3\/8 inches by 10.5 inches, it fits a range of tensioning applications across marine, structural, and outdoor installations. Licensed contractors and rigging professionals are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle is well suited for marine rigging, outdoor cable tensioning, and other applications where atmospheric corrosion resistance is a primary concern. The combination of stainless steel construction and passivated eyes makes it appropriate for saltwater-adjacent environments, fencing, signage support cables, and similar outdoor tensioning work. It ships as a single loose unit and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction with aluminum hex body for corrosion resistance in outdoor and marine environments\u003c\/li\u003e\n  \u003cli\u003ePassivated eyes provide superior resistance to atmospheric corrosion\u003c\/li\u003e\n  \u003cli\u003eNonmagnetic assembly suitable for installations requiring non-ferrous hardware\u003c\/li\u003e\n  \u003cli\u003eHex-shaped body allows adjustment by hand or with a wrench\u003c\/li\u003e\n  \u003cli\u003eHook and eye configuration for versatile line and cable connections\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch by 10.5 inch form factor for medium-duty tensioning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use tensioning component for 3\/8 inch rigging, cable, and line applications in marine and outdoor environments.

Before adjusting or replacing a turnbuckle in a loaded cable or rigging system, relieve tension from the line and secure all connected members. Use a wrench on the hex body to achieve final tensioning; avoid over-tightening beyond the rated load capacity of the connected cables. Follow applicable OSHA and local rigging codes when used in structural or load-bearing applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/8 inches x 10.5 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\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\u003eCorrosion Treatment\u003c\/strong\u003e: Passivated eyes\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: 0.344 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613191372\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: N221978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51346877546802,"sku":"N221978","price":23.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550434.jpg?v=1782093258","url":"https:\/\/voomisupply.com\/products\/national-marker-n221978-hook-eye-turnbuckle-3-8x10-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
