Jacobsen's impact wheel marker positively identifies defective wheels by visibly denting the rim.  A wheel that has been dented is both visually and functionally defective, and cannot be accidentally used as good.

The marker is a complete turnkey unit, requiring only power, trigger and compressed air inputs.  The marker uses a special pneumatic/hydraulic cylinder that generates high pressures without the need for hydraulics.

The marker will work for wheels from 12" to 22" in diameter and from 4" to 12" in width.
