The body is hex-shaped for wrench engagement, manufactured from aluminum with a zinc finish for corrosion resistance. The eyes are steel for added load-bearing strength. This turnbuckle is part of the 2170BC catalog series and is sold individually. It is a standard hardware component installed by riggers, contractors, and maintenance trades in light-duty tensioning applications.\u003c\/p\u003e\n\u003cp\u003eThis turnbuckle suits residential and light commercial applications where cable or rod assemblies require periodic length adjustment or tensioning. The eye-and-eye configuration allows attachment to clevis pins, shackles, or anchor bolts at both ends. The hex body profile allows a wrench to be used for precise adjustment without over-rotating the assembly. Typical installations include wire rope bracing, guy wire systems, and tensioned support lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEye and eye configuration for dual-end attachment to pins, shackles, or anchor points\u003c\/li\u003e\n  \u003cli\u003eHex-shaped aluminum body allows wrench engagement for controlled tensioning\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides corrosion resistance for exposed or outdoor installations\u003c\/li\u003e\n  \u003cli\u003eSteel eyes deliver added tensile strength at the connection points\u003c\/li\u003e\n  \u003cli\u003ePart of the 2170BC catalog series for straightforward replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install eye and eye turnbuckle for light-duty cable and rod tensioning assemblies requiring a 7\/32-inch thread diameter and 6-1\/2-inch body length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by riggers, maintenance technicians, or contractors using standard hand tools. Before adjusting or replacing a turnbuckle in a tensioned system, relieve load from the assembly to prevent sudden release. Thread both eyes evenly onto the body to maintain balanced load distribution and avoid cross-threading. Consult applicable structural or rigging standards for minimum thread engagement and safety factor requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 6-1\/2 inches\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\u003eEye Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Eye and Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613124950\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: N221739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51347335053618,"sku":"N221739","price":29.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550416.jpg?v=1782101906","url":"https:\/\/voomisupply.com\/products\/national-marker-n221739-eye-eye-turnbuckle-zinc-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
