Is your chainsaw chain dull or damaged? This 16-inch replacement chain is a perfect fit for a bunch of popular saws. Specifically, it works great on McCulloch models like the EM300S, EM450S, and MS1630, plus a ton of others including Stihl MS170, MS181, and older 009, 017, 019 series. The specs are spot on: 3/8\ Low Profile (LP) pitch, 0.050\ gauge, and 55 drive links (that's the Oregon S55 equivalent). Made from tough steel to handle cutting firewood, pruning, or general yard work. Brand new in the package. Swapping a chain is way cheaper than buying a new saw. Keep this as a spare or install it now for sharper, safer cuts. Just make sure it matches your bar length and sprocket!
