The Oregon 15" Bar & 2 Chain Combo, with a .325" pitch and .050" gauge, is a versatile and lightweight chainsaw accessory designed for light commercial and occasional users. This narrow-kerf system provides a faster, more efficient cut by removing less wood, making it ideal for saws up to 55cc displacement. The kit includes a durable guide bar with a multi-rivet sprocket nose for long life and two chains, often with a low-vibration design for better control and reduced kickback. It's a popular choice for a wide range of tasks, including limbing, pruning, and felling small to medium-sized trees.
