It operates on compressed air up to 145 psi and delivers an inner holding capacity of 375 lb (1670 N). The U-bar opens to 95 degrees, providing clear access to the workpiece during load and unload cycles. With a height under bar of 2.69 inches and a cylinder bore of 1.26 inches, this clamp is suited for medium-duty production fixturing. It is installed by machinists, tooling technicians, and fixture builders working in automated or semi-automated production lines.\u003c\/p\u003e\n\u003cp\u003eThe 817-U mounts vertically and is intended for use in jigs, fixtures, and workholding stations where repeatable pneumatic clamping is required. The clamp accepts Round and T-Slot sensor configurations, making it compatible with position-sensing setups common in CNC and automated assembly environments. A flanged washer is included. Port size is 1\/8 NPT, which connects directly to standard shop air circuits. Operating temperature range is 14 degrees F to 194 degrees F (-10 degrees C to 90 degrees C), supporting use in a wide range of industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePneumatic actuation with maximum air pressure of 145 psi (10 bar)\u003c\/li\u003e\n  \u003cli\u003eInner holding capacity of 375 lb (1670 N); outer clamping force of 200 lb (890 N)\u003c\/li\u003e\n  \u003cli\u003e95-degree U-bar opening for unobstructed workpiece access\u003c\/li\u003e\n  \u003cli\u003e1\/8 NPT air port for direct connection to standard pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003eRound and T-Slot sensor compatibility for position-sensing integration\u003c\/li\u003e\n  \u003cli\u003eVertical mounting orientation with flanged washer included\u003c\/li\u003e\n  \u003cli\u003eMaximum mechanical advantage of 2.5:1 and 4.1:1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in pneumatic workholding fixtures and tooling stations that accept vertically mounted hold down toggle clamps with 1\/8 NPT air connections and Round or T-Slot sensor interfaces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by tooling technicians or fixture builders. Shut off and bleed all air pressure from the pneumatic circuit before mounting or servicing this clamp. Mounting holes accept 0.27-inch fasteners with a 1.00-inch width spacing and 0.63-inch length spacing between holes. Verify that the supply air pressure does not exceed 145 psi and that air quality meets standard industrial requirements for filtration and lubrication as applicable to the system design.\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 (1670 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Clamping Force\u003c\/strong\u003e: 200 lb (890 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Load Capacity\u003c\/strong\u003e: 225 lb (1005 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Pressure\u003c\/strong\u003e: 145 psi (10 bar)\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: U-Bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Type\u003c\/strong\u003e: Pneumatic\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\u003eHeight Under Bar\u003c\/strong\u003e: 2.69 inches (68.33 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Extension\u003c\/strong\u003e: 2.37 inches (60.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Closed Height\u003c\/strong\u003e: 2.44 inches (62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Closed Length\u003c\/strong\u003e: 6.24 inches (158.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Open Height\u003c\/strong\u003e: 7.51 inches (190.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Open Length\u003c\/strong\u003e: 3.87 inches (98.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Size\u003c\/strong\u003e: 0.27 inches (6.86 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 1.00 inches (25.40 mm)\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\u003eMaximum Mechanical Advantage\u003c\/strong\u003e: 2.5:1 and 4.1:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/8 NPT\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 (-10 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 194 degrees F (90 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.31 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Flanged Washer\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\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":52100762468658,"sku":"817-U","price":253.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/707f436b3bcdf5beff759ff6d5508c0c.jpg?v=1790069301","url":"https:\/\/voomisupply.com\/products\/de-sta-co-817-u-pneumatic-hold-down-toggle-clamp","provider":"Voomi Supply","version":"1.0","type":"link"}
