De-sta-co 81L20-10100 Pneumatic Hold Down Toggle Clamp

Product Description

The DE-STA-CO 81L20-10100 is a pneumatic hold down toggle clamp designed for secure workpiece clamping in production and assembly applications. It features a solid bar with a 90-degree opening arc and an inner holding capacity of 885 pounds. The clamp operates on a vertical mounting orientation and accepts air supply through an M5 port, with a working pressure range of 20 to 130 psi. The 1.57-inch cylinder bore delivers maximum clamping torque of 159 pounds at 72 psi. Height under the bar measures 5.94 inches, making it well suited for applications where consistent and repeatable clamping force is required on a production fixture or jig.

This clamp is intended for industrial and manufacturing environments where pneumatic actuation improves cycle time over manual toggle clamps. Typical installations include welding fixtures, machining jigs, assembly stations, and automated production lines. The closed bar end style and solid bar construction are appropriate for high-cycle-rate operations. The vertical mounting orientation allows direct integration into flat fixture plates. Sensor compatibility supports Round and T-Slot sensor types for position feedback in automated or semi-automated setups.

Compatibility

Designed for vertical-mount fixture plate integration in industrial pneumatic clamping systems. No specific OEM equipment compatibility was provided in the product data.

Installation Notes

Installation is typically performed by industrial maintenance technicians or fixture builders following applicable pneumatic system safety procedures. Depressurize the air supply line before connecting or disconnecting the M5 port fitting. Mount using M6x8 mounting holes at the specified bolt-circle dimensions and verify fastener torque meets fixture plate material requirements. Do not exceed 130 psi supply pressure, and confirm sensor wiring and positioning prior to returning the fixture to production service.
