For the Cletrac crawler fans, we've created the Cletrac OC3 cut-out. The OC3, which was built to replace the HG, was also made by the Oliver corporation in Ohio. The OC3 was as versatile as the HG. Cut from 16 gauge steel and painted with a durable urethane enamel paint and a high gloss clear. We've cut as much detail as possible into this design.
