TriLink�s MC72 chain is a full chisel .325� pitch chain with hardened, chrome squared cutters designed for high-speed, excellent chip clearance in clean conditions. The full chisel chain is preferred by professional users. This chain is UL tested and approved for low kickback safety. TriLink chain features the Centri-Lube� oil distribution system. Centri-Lube� pulls oil from the bar and distributes to the chain�s rivets reducing stretch, limiting field adjustments, and extending the life of the chain.
