Actuated by compressed air rather than manual effort, it delivers an inner holding capacity of 450 pounds (2000 N) at a maximum operating pressure of 145 psi (10 bar). The solid bar opens to 95 degrees, providing clear access to the workpiece between cycles. The 817-S is installed by tool-and-die technicians, fixture builders, and automation integrators who need reliable pneumatic actuation on jigs, fixtures, and production tooling.\u003c\/p\u003e\u003cp\u003eThis clamp is suited for vertical mounting on production fixtures in light-to-medium industrial environments. The 1\/8 NPT port allows direct connection to standard shop air lines, and the round and T-slot sensor compatibility supports integration with cycle-sensing or part-presence detection systems. The clamp includes a bolt retainer and operates across a temperature range of 14 degrees F to 194 degrees F, making it appropriate for both ambient and moderately heated production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePneumatic actuation rated to 145 psi maximum air pressure for consistent, hands-free clamping\u003c\/li\u003e\n\u003cli\u003eInner holding capacity of 450 lb (2000 N) with a mechanical advantage up to 4.25:1\u003c\/li\u003e\n\u003cli\u003eSolid bar design with 95-degree opening for unobstructed workpiece loading and unloading\u003c\/li\u003e\n\u003cli\u003e1\/8 NPT air port for straightforward connection to standard pneumatic supply lines\u003c\/li\u003e\n\u003cli\u003eCompatible with round and T-slot sensors for automation and cycle-detection integration\u003c\/li\u003e\n\u003cli\u003eIncludes bolt retainer; vertical mounting orientation with 0.27-inch mounting holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pneumatic hold down toggle clamp for industrial jigs, fixtures, and production tooling requiring vertical-mount pneumatic actuation with sensor integration capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by fixture builders or industrial maintenance technicians familiar with pneumatic circuit assembly. Isolate and bleed the air supply before connecting or disconnecting the clamp from the pneumatic line. Confirm that the shop air supply does not exceed the 145 psi maximum rated pressure. Mounting hardware should be torqued per facility standards using the 0.27-inch mounting holes in a vertical orientation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Type\u003c\/strong\u003e: Pneumatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Holding Capacity\u003c\/strong\u003e: 450 lb (2000 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: Solid\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: 2.44 inches (62 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\u003eCylinder Bore Size\u003c\/strong\u003e: 1.26 inches (32 mm)\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\u003eMounting Orientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/8 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Mechanical Advantage\u003c\/strong\u003e: 4.25:1\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 (-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: Bolt Retainer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":52092152185138,"sku":"817-S","price":267.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f1b5a0a1e8bbc52adff787ace2392a0.jpg?v=1790063641","url":"https:\/\/voomisupply.com\/products\/de-sta-co-817-s-pneumatic-hold-down-toggle-clamp-450-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
