Package List: 1 x Chain Note: The drive link is the triangular part of the chain located in the guide bar groove. The gauge is the width of the guide rod slot opening (or the thickness of the driving link). The most common gauges are 0.043, 0.050, 0.058, and 0.063. Pitch is the actual measured distance between any three rivet heads on the chain saw divided by 2. The most common pitches are 1/4in, 3/8LP (low‑pro), .325, 3/8in. The pitch and specifications of the chain are not easy to measure, so it is best to use the chain manufacturing codes of the old chain stamped on the drive link to determine the pitch and specifications of the chain
