Post Markers Cottrell has recently started processing some tubing parts with laser technology. As a result, our customers will be seeing a difference in the “marker” hole on our trailers. The intention of this hole is to give the operator a quick reference of pin off locations from side to side on the equipment. The smaller, through hole does not impact the structural integrity of the equipment and will soon become our standard. If you have any questions about this change, please contact your Cottrell representative. “Our expertise is your Advantage on the Road!”
