The Fin Contour Device (FCD) was invented by Ron McCormick of McCormick & Associates. This device allows the fin cooler to accommodate the shape of the bushing as it ages (sags). With a quick turn of a screw, the fin cooler mimics the shape of the aging bushing. 

The Fin Contour Device improves operation and efficiency of the fin cooler, extending the life of the bushing by one to two months. The FCD is reusable.
