Specs: TriLink’s full chisel .325″ pitch chain is manufactured with hardened, chrome squared cutters designed for high-speed, excellent chip clearance in clean conditions. The .063” gauge design provides more chip clearance with each cut. 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. Replaces OEM Numbers: Stens: 099-5257
