The Precision Fin Device (PFD) was invented by Ron McCormick of McCormick & Associates. This device provides precision and simplification in the positioning of fin coolers. 

During fin cooler replacement, the new fin cooler is placed in the PFD which exactly replicates the position of the spent fin cooler. The PFD improves bushing efficiency and assists the bushing operator by decreasing the time it takes to install and position fin coolers. The PFD is reusable.
