Constructed from 304 stainless steel, it delivers corrosion resistance in wet, humid, or chemically active environments. The clamp accepts a 5\/8 inch rod and accommodates flanges up to 3\/4 inch thick, with a rated load capacity of 550 pounds. Licensed trades including HVAC mechanics, pipefitters, and plumbers install this type of hardware when securing pipe runs to structural steel beams or channels.\u003c\/p\u003e\n\u003cp\u003eThis C-Clamp with Locknut is used in commercial and industrial mechanical systems where pipe support assemblies attach to beam flanges. The locknut provides a positive lock to prevent vibration-induced loosening over time. At 0.6 pounds, the fitting is lightweight enough for overhead installation without adding significant load to the support structure. It is suited for both new construction and retrofit applications where a stainless steel hanger component is required for corrosion resistance or specification compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003e550 pound load capacity for robust pipe support applications\u003c\/li\u003e\n  \u003cli\u003eAccepts 5\/8 inch threaded rod for standard hanger assemblies\u003c\/li\u003e\n  \u003cli\u003eMaximum flange thickness of 3\/4 inch for compatibility with common structural steel sections\u003c\/li\u003e\n  \u003cli\u003eIntegrated locknut prevents loosening from vibration\u003c\/li\u003e\n  \u003cli\u003ecULus Listed, FM Approved, and compliant with MSS SP-69 Type 23, SP-58, and UL-ULC standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard pipe support component for mechanical systems using 5\/8 inch threaded rod hanger assemblies with structural beam flange connections up to 3\/4 inch thick.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter, plumber, or HVAC mechanic in accordance with applicable mechanical codes such as the IFGC or IPC and pipe support standards. Verify that the beam flange thickness does not exceed 3\/4 inch and that the rod size matches the specified 5\/8 inch thread before assembly. Torque the locknut firmly to secure the clamp against the flange prior to loading the hanger assembly. Always de-energize or depressurize associated systems before working in the vicinity of existing pipe runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: C-Clamp with Locknut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 550 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flange Thickness\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: cULus Listed, FM Approved, MSS SP-69 Type 23, MSS SP-58, UL-ULC Listed\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: EMPIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21LSS0058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMPIRE INDUSTRIES","offers":[{"title":"Default Title","offer_id":51718557434162,"sku":"21LSS0058","price":53.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/362b1361edef40d8995d126d39e0f598.jpg?v=1788554233","url":"https:\/\/voomisupply.com\/products\/empire-21lss0058-c-clamp-locknut-550-lb-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
