At 9 inches in overall length, this clamp uses a hardened chain loop in place of a conventional lower jaw, allowing it to wrap around pipes, curved stock, and uneven surfaces while the locking mechanism cinches down and holds position. It is a hand tool built for fabrication shops, pipefitters, welders, and ironworkers who need a repeatable, firm hold on non-flat work without using a vise or fixture.\u003c\/p\u003e\n\u003cp\u003eThe IR27ZR is suited for work-holding applications in both shop and field environments. Typical use cases include welding and tack-welding round tubing, holding pipe sections during fit-up, and clamping irregular castings or structural shapes during layout and assembly. Its 20R designation identifies the chain-style jaw configuration, which accommodates a wider range of workpiece profiles than a standard curved jaw locking plier.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20R locking chain clamp configuration grips round, irregular, and odd-shaped workpieces\u003c\/li\u003e\n  \u003cli\u003e9-inch overall length suited for medium-duty work-holding tasks\u003c\/li\u003e\n  \u003cli\u003eChain loop lower jaw replaces fixed curved jaw for versatile fitment around pipes and profiles\u003c\/li\u003e\n  \u003cli\u003eLocking mechanism holds set position without continuous hand pressure\u003c\/li\u003e\n  \u003cli\u003eSold individually  -  minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style work-holding clamp for general fabrication, pipefitting, and welding applications requiring a chain-style locking grip on round or irregular workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo power source or shutoff is required for hand tool use. Adjust the jaw-opening screw before applying the chain loop to the workpiece to avoid over-stressing the locking mechanism. Inspect the chain and pivot points for wear or deformation before each use, and replace the clamp if any component shows cracking or excessive play. Follow applicable shop safety practices when clamping workpieces near welding or cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 20R Locking Chain Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: Locking Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Hand Tools\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR27ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":68081475158322,"sku":"IR27ZR","price":49.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49d011ed284132ce91d5752cd7140344.jpg?v=1793140278","url":"https:\/\/voomisupply.com\/products\/irwin-ir27zr-locking-chain-clamp-9-inches-1","provider":"Voomi Supply","version":"1.0","type":"link"}
