Specs: TriLink’s semi-chisel 3/8” LP pitch chain contains hardened, chrome cutters for fast, smooth cutting in dirty conditions. The .063” gauge is larger than standard providing a slightly bigger “bite” while cutting. The .050” gauge is standard for most chainsaws. All TriLink semi-chisel chain is a 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: 090-5257
