•Cup and combo chains come standard with 2-pitch, anti-back flex design preventing chain links from "flexing" back in tough soil conditions.
•4" and 6" chain widths available in soil/cup, combo cup/rock, welded rock, and bullet style rock tooth configurations. Lengths for 24" (61 cm) and 36" (91.5 cm) booms (48" (122 cm) boom chains available in soil/cup and combo cup/rock only).
