The body is hex-shaped, allowing adjustment by hand or with a standard wrench. Eyes are passivated for enhanced corrosion resistance beyond standard stainless steel. The material is nonmagnetic and resistant to atmospheric corrosion, making this turnbuckle well suited to demanding environments. The 3\/16-inch thread diameter and 5-1\/2-inch body length make it appropriate for light-to-medium tensioning applications. Licensed riggers, marine mechanics, and general contractors typically install this hardware in both marine and land-based settings.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle is used in marine rigging, outdoor cable assemblies, fence tensioning, antenna stays, and similar applications where corrosion resistance and reliable tension adjustment are required. Its nonmagnetic stainless steel construction performs well in saltwater and high-humidity environments. The passivated eyes provide additional protection at the contact points where corrosion most commonly initiates. It is sold individually and is suited to both new installations and replacement work on existing cable or wire rope assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction with aluminum body for corrosion resistance in marine and outdoor environments\u003c\/li\u003e\n  \u003cli\u003ePassivated eyes provide superior corrosion resistance at the load-bearing contact points\u003c\/li\u003e\n  \u003cli\u003eNonmagnetic material suitable for applications where magnetic interference is a concern\u003c\/li\u003e\n  \u003cli\u003eHex-shaped body allows hand adjustment or wrench tightening for precise tensioning\u003c\/li\u003e\n  \u003cli\u003eEye-eye configuration accepts looped cable ends, wire rope thimbles, or threaded hooks on both ends\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or new-installation eye-eye turnbuckle for marine rigging, outdoor cable tensioning, and general-purpose wire rope assemblies.

Inspect all mating hardware, thimbles, and anchor points before installation. Do not exceed the working load limit of the weakest component in the assembly. Secure with locking wire or jam nuts after final tensioning to prevent loosening under vibration or dynamic loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Eye-Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\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 Treatment\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: 0.064 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613191327\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: N221820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51347438010674,"sku":"N221820","price":37.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550411.jpg?v=1782104969","url":"https:\/\/voomisupply.com\/products\/national-marker-n221820-eye-eye-turnbuckle-3-16-x-5-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
