De-sta-co 8021 Pneumatic Hold Down Toggle Clamp 390 Lb

Product Description

The DE-STA-CO 8021 is a pneumatic hold down toggle clamp designed to secure workpieces in industrial fixturing, welding, and assembly applications. Actuated by compressed air through a 1/8 NPT port, the clamp delivers an inner holding capacity of 390 pounds (1,735 N) using a 1.26-inch cylinder bore. The solid bar opens 90 degrees and provides 1.56 inches of clearance height under the bar, giving operators consistent and repeatable clamping without manual effort. Horizontal mounting orientation and an included flanged base make integration into fixture plates and production tooling straightforward for machine builders and fixture technicians.

This clamp is suited for production environments where pneumatic actuation improves cycle time and operator ergonomics. Typical applications include welding fixtures, machining jigs, assembly stations, and automated workholding setups. The sensor compatibility with both round and T-slot sensor types supports position feedback integration in automated lines. It operates across a temperature range of 14 degrees F to 194 degrees F, making it appropriate for standard industrial shop environments.

Compatibility

Designed for use in industrial fixturing and workholding systems requiring pneumatic hold down clamping with horizontal mounting orientation and 1/8 NPT pneumatic connections.

Installation Notes

Installation should be performed by qualified fixture builders or industrial maintenance technicians familiar with pneumatic tooling systems. Disconnect and lock out the air supply before mounting or servicing the clamp. Ensure the supply air is clean, dry, and regulated to the maximum rated pressure of 10 bar before connecting to the 1/8 NPT port. Verify mounting hole alignment using the specified hole pattern dimensions before final fastener torque.
