De-sta-co 8071 Pneumatic Hold Down Toggle Clamp 450 Lb

Product Description

The DE-STA-CO 8071 is a pneumatic hold down toggle clamp designed for industrial workholding applications where consistent, repeatable clamping force is required. Powered by compressed air through a 1/8 NPT port, the clamp delivers an inner holding capacity of 450 pounds (2000 N) and a maximum mechanical advantage of up to 4.2:1. The solid bar opens to 90 degrees and sits 1.65 inches above the work surface when closed, keeping the clamp profile low in high-cycle fixture setups. Licensed millwrights, machine builders, and fixture technicians are the primary installers of this clamp in production and assembly environments.

The 8071 is suited for horizontal mounting in pneumatic fixturing systems on machining centers, welding tables, assembly jigs, and automated production lines. The 1.57-inch cylinder bore drives consistent actuation across high-volume cycles. Sensor compatibility includes round and T-slot styles, making it adaptable to automated detection setups. A bolt retainer is included. Mounting holes are spaced 1.97 inches lengthwise and 1.56 inches in width, accommodating standard fixture plate layouts.

Key Features

Compatibility

Designed as an OEM-style pneumatic hold down toggle clamp for use in industrial fixturing, jig, and workholding applications requiring horizontal mounting and compressed-air actuation.

Installation Notes

Installation should be performed by qualified millwrights or fixture technicians following the equipment manufacturer guidelines and applicable workplace safety codes. Depressurize the pneumatic supply line completely before mounting, adjusting, or servicing the clamp. Confirm that supply air pressure does not exceed the maximum rated pressure of 10 bar before connecting the air line. Verify mounting hole alignment and torque fasteners to the fixture plate specifications provided by the fixture designer.
