Actuated by compressed air through a 1\/8 NPT port, it generates an inner holding capacity of 375 pounds (1,670 N) using a 1.26-inch cylinder bore. The solid bar opens to a 95-degree arc, providing 2.69 inches of clearance height under the bar for loading and unloading workpieces. A flanged washer is included. This clamp is installed by manufacturing technicians, tool-and-die makers, and fixture builders working with pneumatic automation systems.\u003c\/p\u003e\n\u003cp\u003eThis clamp is suited for vertical mounting on production fixtures, jigs, and worktables in light to medium industrial environments. Its pneumatic actuation makes it appropriate for applications requiring repeatable clamping cycles without manual lever operation. The closed bar style and sensor compatibility with round and T-slot sensor profiles allow integration with automated presence-detection systems. Operating temperature range spans 14 degrees F to 194 degrees F, supporting use in temperature-variable shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e375 lb (1,670 N) inner holding capacity for secure workpiece retention\u003c\/li\u003e\n  \u003cli\u003ePneumatic actuation via 1\/8 NPT port with maximum 10 bar (145 psi) air pressure\u003c\/li\u003e\n  \u003cli\u003e95-degree bar opening angle with 2.69 inches of height under bar clearance\u003c\/li\u003e\n  \u003cli\u003e1.26-inch cylinder bore with up to 2.5:1 and 4.1:1 maximum mechanical advantage\u003c\/li\u003e\n  \u003cli\u003eCompatible with round and T-slot sensor profiles for automation integration\u003c\/li\u003e\n  \u003cli\u003eVertical mounting orientation with flanged washer included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pneumatic hold down toggle clamp for use in industrial fixturing and workholding applications requiring vertical mounting and automated pneumatic actuation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by fixture builders or maintenance technicians familiar with pneumatic tooling and workholding systems. Disconnect and bleed the air supply before mounting or servicing this clamp. Mount vertically using the specified 0.27-inch mounting holes spaced 0.63 inches apart lengthwise and 1.00 inch apart widthwise, and torque fasteners per your fixture design requirements. Verify air line pressure does not exceed 10 bar before commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Capacity (Inner)\u003c\/strong\u003e: 375 lb (1,670 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Clamping Force\u003c\/strong\u003e: 1,005 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Pressure\u003c\/strong\u003e: 10 bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/8 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCylinder Bore Size\u003c\/strong\u003e: 1.26 inches (32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Opening\u003c\/strong\u003e: 95 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Style\u003c\/strong\u003e: Solid, Closed End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Extension\u003c\/strong\u003e: 2.37 inches (60.2 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Under Bar\u003c\/strong\u003e: 2.69 inches (68.33 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Closed Height\u003c\/strong\u003e: 7.51 inches (190.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Closed Length\u003c\/strong\u003e: 6.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Open Length\u003c\/strong\u003e: 3.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Size\u003c\/strong\u003e: 0.27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Distance Between Mount Holes\u003c\/strong\u003e: 0.63 inches (16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 1.00 inch (25.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Mechanical Advantage\u003c\/strong\u003e: 2.5:1 and 4.1:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor Compatibility\u003c\/strong\u003e: Round, T-Slot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 14 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 194 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Type\u003c\/strong\u003e: Pneumatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Flanged Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162900\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: DE-STA-CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 817-U-LC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":67906526609714,"sku":"817-U-LC","price":119.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_bf1b8e9d-82c4-49b5-9bb6-4f7a47825c42.jpg?v=1791168824","url":"https:\/\/voomisupply.com\/products\/de-sta-co-817-u-lc-pneumatic-hold-down-toggle-clamp-375-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
