Bar-Lok Quick-Acting Screw Clamps

Definitely the strongest quick-acting screw clamp available. The patented grooved-bar design works smoothly and positively - just slide the bar forward to contact the workpiece, then turn clockwise to apply force. To unclamp, turn counterclockwise and slide the bar back. As strong as a standard screw clamp, but much faster.

I have some very old clamps with this system. I've never seen anything like that.

great! I'm building a gpu anti-sag cylinder and i needed that mechanism to stop the extruded part from moving.
