This PowerKing chain is built for 20"/510mm bars running a 0.325" pitch and 0.058" gauge with 76 drive links. It will fit any chainsaw from any manufacturer — the brand on the saw body is immaterial. What determines compatibility is the pitch of your drive sprocket, the gauge of your bar groove, and the number of drive links needed to span the bar. All three must match; getting one wrong means the chain will either not fit or will wear prematurely and run unsafely.The 0.058" gauge makes this a solid choice for petrol saws in the mid-to-high power bracket, where thinner chains can flex under the torque generated during hard cuts. The 20" length gives you the capacity to work through significant timber in a single pass, which matters on felling jobs where efficiency is as important as raw power.
