It delivers 770 pounds of clamping pressure through a lever-style handle, allowing fast one-handed adjustments along the rail without sacrificing holding force. The forged steel frame and forged steel pad material provide the structural rigidity needed for repeated heavy-use cycles. With an 8-inch maximum capacity and a 4-inch throat depth, this clamp handles a wide range of workpiece sizes in both shop and field settings. A nickel finish adds corrosion resistance to the forged body.\u003c\/p\u003e\n\u003cp\u003eThe G20L belongs to GIBRALTAR's Series G bar clamp line. It is suited for metalworking, millwright, and fabrication trades where repeatable, high-pressure workholding is required. The lever handle design speeds up setup time in production environments, making it a practical choice for welding fixturing, assembly jigs, and machining setups. The alloy steel spindle maintains thread integrity under sustained clamping loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e770-pound clamping pressure for secure workholding under heavy loads\u003c\/li\u003e\n  \u003cli\u003eLever-style handle allows fast single-hand sliding adjustment\u003c\/li\u003e\n  \u003cli\u003eForged steel frame and pad for maximum rigidity and durability\u003c\/li\u003e\n  \u003cli\u003eAlloy steel spindle resists thread wear under repeated high-force use\u003c\/li\u003e\n  \u003cli\u003e4-inch throat depth accommodates thicker workpieces and flanged edges\u003c\/li\u003e\n  \u003cli\u003eNickel finish provides added corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use clamp within the GIBRALTAR Series G sliding arm bar clamp family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis clamp is installed and operated by machinists, fabricators, welders, and millwrights. Before applying clamping pressure, confirm the workpiece is properly seated and the rail is fully engaged in the sliding arm. Inspect the spindle threads and pad surfaces before each use for wear or damage. Always release clamping pressure fully before repositioning the sliding arm along the rail.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Pressure\u003c\/strong\u003e: 770 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRail Size\u003c\/strong\u003e: 19.50 x 9.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Material\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 11.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112100\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G20L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723588731186,"sku":"G20L","price":76.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d67b3b0e6a50a3854c3463ff667ebd71.jpg?v=1788606791","url":"https:\/\/voomisupply.com\/products\/gibraltar-g20l-sliding-arm-bar-clamp-8-in-4-in-throat","provider":"Voomi Supply","version":"1.0","type":"link"}
