Rated for a maximum air pressure of 250 psi (17 bar), this clamp delivers an inner holding capacity of 99 lb (440 N) and an outer clamping force of 93 lb (413 N). The solid bar style swings through a 99-degree arc, and the height under bar measures 0.68 inches, making it well suited for low-profile clamping setups. A spindle assembly is included. The clamp is installed by licensed or qualified machine-tool and fixture technicians in production and fabrication environments.\u003c\/p\u003e\u003cp\u003eThe 812-U-RC is used in horizontal-mounting orientations on jigs, fixtures, and production tooling where repeatable pneumatic clamping is needed. Typical applications include assembly lines, welding fixtures, CNC workholding setups, and inspection stations. The M5 port integrates directly into standard pneumatic control circuits. The clamp operates reliably across a temperature range of -9 degrees F to 165 degrees F, making it appropriate for both standard indoor production environments and moderately cold workspaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAir-actuated hold down design rated to 250 psi maximum operating pressure\u003c\/li\u003e\n\u003cli\u003eInner holding capacity of 99 lb (440 N) with outer clamping force of 93 lb (413 N)\u003c\/li\u003e\n\u003cli\u003eSolid bar with 99-degree opening arc and 0.68-inch height under bar for low-profile clearance\u003c\/li\u003e\n\u003cli\u003eM5 port size for direct integration with standard pneumatic plumbing\u003c\/li\u003e\n\u003cli\u003eMaximum mechanical advantage of 2.9:1 to 4.3:1 depending on configuration\u003c\/li\u003e\n\u003cli\u003eSpindle assembly included; spindle thread size M5\u003c\/li\u003e\n\u003cli\u003eHorizontal mounting orientation with mounting holes spaced 0.63 inches (length) by 0.94 inches (width)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pneumatic hold down toggle clamp for use in standard horizontal-mount fixturing and workholding applications requiring M5 pneumatic port connections and solid-bar clamping geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified fixture technicians or maintenance personnel familiar with pneumatic systems and machine guarding requirements. Depressurize the pneumatic supply line completely before connecting or disconnecting the M5 port fitting. Secure the clamp body to the fixture plate using appropriately sized fasteners through the 0.17-inch mounting holes before introducing air pressure. Verify all pneumatic connections are leak-free and that the clamp bar has adequate clearance through its full 99-degree swing before placing the fixture into service.\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: 99 lb (440 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Clamping Force\u003c\/strong\u003e: 93 lb (413 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Air Pressure\u003c\/strong\u003e: 250 psi (17 bar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBar Opening\u003c\/strong\u003e: 99 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\u003eHeight Under Bar\u003c\/strong\u003e: 0.68 inches (17.27 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Mechanical Advantage\u003c\/strong\u003e: 2.9:1 to 4.3:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: M5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Thread Size\u003c\/strong\u003e: M5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Size\u003c\/strong\u003e: 0.17 inches (4.32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Distance Between Mount Holes\u003c\/strong\u003e: 0.63 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 0.94 inches (23.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -9 degrees F (-23 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 165 degrees F (74 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Spindle Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162900\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: 812-U-RC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":67596393021746,"sku":"812-U-RC","price":85.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_08f30e7b-0490-478c-923e-95e7f5afe432.jpg?v=1790424007","url":"https:\/\/voomisupply.com\/products\/de-sta-co-812-u-rc-pneumatic-hold-down-toggle-clamp","provider":"Voomi Supply","version":"1.0","type":"link"}
