De-sta-co 860 Pneumatic Hold Down Toggle Clamp 3000 Lb

Product Description

The DE-STA-CO 860 is a pneumatic hold down toggle clamp designed for high-force workholding applications in production and assembly environments. It delivers a holding capacity of 3000 pounds with a maximum mechanical advantage of 5:1, using compressed air supplied through a 3/8 NPT port at up to 125 psi. The clamp features a 180-degree bar opening, a 2.0-inch cylinder bore, and a vertically oriented mounting configuration. A magnetic ring is included for cylinder position sensing. Licensed HVAC and trade professionals working in automated fixture setups, welding jigs, and machining cells will recognize this as a robust, high-cycle clamping solution.

The 860 is suited for vertical hold down applications in industrial production lines, welding fixtures, machining centers, and assembly jigs where pneumatic actuation is preferred over manual toggle clamping. The vertical mounting orientation makes it a practical choice for flat fixture plates and table-mounted workholding systems. Its high holding capacity and generous bar opening make it appropriate for clamping larger or irregularly shaped workpieces in repetitive cycle operations.

Key Features

• 3000 lb holding capacity with 5:1 maximum mechanical advantage
• 180-degree bar opening for wide workpiece clearance
• 2.0-inch cylinder bore for consistent pneumatic force output
• 3/8 NPT air port rated to 125 psi
• Magnetic ring included for cylinder position sensing and automation integration
• Vertical mounting orientation with defined mount hole pattern

Compatibility

Designed as an OEM-style pneumatic hold down toggle clamp for vertical mount fixture applications requiring a 3/8 NPT air supply and a 180-degree bar opening.

Installation Notes

Installation should be performed by a qualified mechanical or automation technician familiar with pneumatic circuit design and workholding fixture standards. Depressurize the air supply line fully before mounting, connecting, or servicing the clamp. Ensure the mounting surface is flat and that fasteners are sized to the 0.34-inch mounting holes. Verify air supply does not exceed the rated 125 psi and that all pneumatic fittings are leak-free before cycling the clamp under load.
