Built with a cast iron body, it delivers a maximum opening capacity of 5 inches and a throat depth of 3.25 inches, making it well-suited for a wide range of bench and field applications. The clamp handles a load capacity of 1,500 pounds, giving it enough clamping force for typical trade and light industrial use. The 9\/16-inch screw diameter provides solid thread engagement and controlled pressure application. This clamp is a standard tool for HVAC technicians, pipefitters, electricians, plumbers, and general tradespeople who need reliable workholding during installation or fabrication work.\u003c\/p\u003e\u003cp\u003eThe IRWIN 225105 fits standard-depth clamping applications in both residential and commercial settings. It is commonly used to hold pipe, duct sections, conduit assemblies, brackets, and structural components in place while fastening, welding, or bonding operations are completed. The 5-inch opening accommodates a variety of material thicknesses and stacked assemblies encountered in everyday trade work. The compact cast iron frame keeps weight manageable at 4.7 pounds while maintaining structural rigidity under load.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-inch maximum opening capacity accommodates a wide range of workpiece sizes\u003c\/li\u003e\n\u003cli\u003e3.25-inch standard throat depth for reaching past edges and flanges\u003c\/li\u003e\n\u003cli\u003e1,500-pound load capacity rated for regular-duty clamping tasks\u003c\/li\u003e\n\u003cli\u003eCast iron body construction provides rigidity and durability\u003c\/li\u003e\n\u003cli\u003e9\/16-inch screw diameter for positive thread engagement and controlled pressure\u003c\/li\u003e\n\u003cli\u003eMinimum opening of 0 inches allows clamping of thin or flush materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose regular-duty C-clamp suitable for use in HVAC, plumbing, electrical, fabrication, and general construction trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eC-clamps should be seated squarely on the workpiece before applying clamping force to prevent slipping or marring. Do not exceed the rated load capacity, as overloading a cast iron clamp body can cause brittle fracture. Use jaw pads or scrap material to protect finished surfaces when clamping soft metals or coated components. Inspect the screw threads and swivel pad for wear or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: Standard C-Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Opening Capacity\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Opening Capacity\u003c\/strong\u003e: 0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 1,500 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Diameter\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Regular-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112120\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 225105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51543382130994,"sku":"225105","price":21.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9faeb000bda7d390617e26c05f3c877f.jpg?v=1785917553","url":"https:\/\/voomisupply.com\/products\/irwin-225105-c-clamp-5-in-regular-duty-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
