It delivers a maximum jaw opening of 36 inches and a load capacity of 6000 pounds, making it a serious tool for trade professionals who need reliable, high-force clamping across wide workpieces. The 5\/8-inch spindle diameter provides the mechanical advantage needed to apply consistent, controlled pressure. The 1-7\/8 by 1-13\/16 inch clamp face distributes load evenly to reduce surface damage on workpieces. Installers, fabricators, and millwrights rely on this class of clamp for structural assemblies, door and window framing, and heavy panel work.\u003c\/p\u003e\n\u003cp\u003eThe WILTON 21803 suits residential and commercial construction environments as well as shop fabrication settings. It is commonly used when assembling large frames, clamping glued panels, securing structural components during welding or fastening, and holding workpieces in position during layout and marking. The 36-inch opening accommodates wide assemblies that smaller bar clamps cannot span. The throat depth of 1-13\/16 inches limits reach from the edge of the workpiece, which should be factored into layout planning for deep assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e36-inch maximum jaw opening handles wide workpieces and large frame assemblies\u003c\/li\u003e\n  \u003cli\u003e6000-pound load capacity rated for heavy-duty clamping force\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch spindle diameter provides controlled, high-torque actuation\u003c\/li\u003e\n  \u003cli\u003e1-7\/8 by 1-13\/16 inch clamp face spreads clamping load to protect workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003e1-13\/16 inch throat depth for consistent edge clamping geometry\u003c\/li\u003e\n  \u003cli\u003eI-bar construction reduces weight relative to full-bar designs while maintaining rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty I-bar clamp suitable for general fabrication, woodworking, and structural assembly applications requiring a 36-inch jaw opening and high clamping force.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways inspect the clamp bar and spindle threads for damage before applying load. Position the clamp face squarely against the workpiece to avoid slipping under load, which can cause workpiece movement or injury. Do not exceed the rated 6000-pound load capacity. When using on finished or soft surfaces, place protective pads between the clamp face and the workpiece to prevent marring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Jaw Opening\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 6000 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Face Dimensions\u003c\/strong\u003e: 1-7\/8 x 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\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: WILTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILTON","offers":[{"title":"Default Title","offer_id":51344951181618,"sku":"21803","price":102.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546549.jpg?v=1782046603","url":"https:\/\/voomisupply.com\/products\/wilton-21803-i-bar-clamp-36-inch-6000-lb-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
