Revolving Hook Clamp, Alpha 28

This clamp allows precise placement of the clamping head on the workpiece and swings out of the way when unclamped. It is operated by a hex key on the top which moves the clamping arm up and down and allows the arm to swing freely when loose.

The clamp can be set down anywhere along its 90-degree swing. The clamp can also be used to push up instead of down.
