Built from malleable iron with an electro-galvanized finish, it resists corrosion in typical indoor service environments. The clamp accepts a 1\/2-13 threaded rod and supports a load capacity of 1,300 pounds, making it suitable for hanging conduit, pipe, duct, and other trade hardware from I-beams and wide-flange structural members. It is rated to CSA LR-63683 and intended for use by licensed electricians, pipefitters, plumbers, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThe 503SC suits commercial and industrial construction where threaded-rod hanger assemblies attach to exposed structural steel. It fits flanges up to 1 inch thick, covering a wide range of standard structural steel sections encountered in steel-frame buildings, mechanical rooms, and open-ceiling commercial spaces. Contractors use it as a primary point of attachment in seismic and non-seismic hanger assemblies where code-required load ratings must be documented and met.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1,300 lb load capacity for heavy-duty hanger applications\u003c\/li\u003e\n\u003cli\u003eAccepts 1\/2-13 threaded rod for compatibility with standard hanger hardware\u003c\/li\u003e\n\u003cli\u003eFits flanges up to 1 inch thick\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction provides strength and impact resistance\u003c\/li\u003e\n\u003cli\u003eElectro-galvanized finish for corrosion protection in indoor environments\u003c\/li\u003e\n\u003cli\u003eCSA LR-63683 rated for code-documented installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style standard beam clamp for use with 1\/2-13 threaded rod hanger systems on structural steel flanges up to 1 inch in thickness, consistent with common mechanical, electrical, and plumbing suspension assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed electricians, pipefitters, or mechanical contractors working from an elevated work platform or scaffold. De-energize or isolate any energized systems in the work area before attaching hanger assemblies overhead. Verify that the structural steel flange is within the 1-inch maximum thickness and that the total suspended load does not exceed the 1,300 lb rated capacity. Follow applicable codes including NFPA 70, IFGC, and IPC for hanger spacing and load requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: Standard Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Electro Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 1300 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flange Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA LR-63683\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THOMAS BETTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 503SC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51540220346674,"sku":"503SC","price":33.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dac3b90bbbc5f8ae59957cc8341a04c5.jpg?v=1785849297","url":"https:\/\/voomisupply.com\/products\/thomas-betts-503sc-standard-clamp-1300-lb-malleable-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
