Constructed from carbon steel with a cadmium plating finish for corrosion resistance, this handle features a reamed 1\/2 inch hole for precise shaft or stud engagement. The 1 inch ball diameter provides a comfortable, firm grip during clamping and adjustment operations. Licensed machinists, toolroom technicians, and fixture builders typically specify this style of handle for jigs, vises, and machine tool setups that demand accurate manual actuation.\u003c\/p\u003e\n\u003cp\u003eThis offset clamping handle suits industrial and manufacturing environments where single-arm offset geometry is needed to clear adjacent hardware or provide additional torque leverage. The 3 inch arm spread and 0.375 inch arm diameter make it appropriate for light- to medium-duty fixture work on mills, drill presses, rotary tables, and similar tooling. The cadmium plated finish helps maintain dimensional integrity in moderate shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle offset arm configuration provides clearance over obstructions in tight fixture layouts\u003c\/li\u003e\n  \u003cli\u003eReamed 1\/2 inch hole ensures close dimensional tolerance for stud or shaft fit\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction with cadmium plating for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1 inch ball diameter for solid manual grip during clamping operations\u003c\/li\u003e\n  \u003cli\u003e3 inch arm spread delivers adequate leverage for hand-tightening applications\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch hole depth accommodates standard stud engagement lengths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit clamping handle for jigs, fixtures, and machine tool assemblies requiring a single offset arm with a 1\/2 inch reamed hole and 1-1\/4 inch hub diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by toolroom machinists or fixture technicians using standard hand tools. Ensure the mating stud or shaft is within the tolerance range of the reamed hole before assembly to avoid binding. De-energize and lock out any associated machinery before servicing or replacing clamping hardware on active fixtures. Avoid applying excessive impact force to the ball or arm, as this may affect the reamed hole dimension over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Clamping Handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Arms\u003c\/strong\u003e: 1 Offset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Cadmium Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Type\u003c\/strong\u003e: Reamed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Spread\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 pounds\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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51959856136498,"sku":"28906","price":26.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/584ed54f4cc734a3762f718a54d1a8b0.jpg?v=1789945936","url":"https:\/\/voomisupply.com\/products\/jergens-28906-offset-clamping-handle-1-2-inch-reamed-hole","provider":"Voomi Supply","version":"1.0","type":"link"}
