Use multiple fixtures to create a workholding system capable of clamping and unclamping multiple parts with the push of a button. When powered hydraulically, these fixtures exert five times the force of standard air-operated collet fixtures, making them good for heavy machining requiring an extra-tight hold. Used with air, they provide the same holding power as standard fixtures. Maximum clamping force depends on the pressure of your system. To calculate the clamping force on your collet, multiply inlet pressure by 7.5. Use 5C collets (sold separately) to grip and release parts on milling machines and drill presses. During clamping, the collet remains stationary to ensure the workpiece does too. A through-hole on the bottom of the fixture accommodates long workpieces.

Connector bushings join multiple fixtures. Two connectors are needed for each fixture after the first.
