Stiles: Two vertical channels, one on each side of the car, running parallel to the rails. The stiles connect to the cross-head and the bolster. They provide a mounting point for one end of the brace rods, and a mounting point for the platen plate to attach the piston to the car. The length of the stiles determines the sling height. Because the plungers mount near the top of the stiles, the jack length (or travel) can be a determining factor as to the stile length. This concept is most prevalent on single stage jacks.
