I picked up a spare chain for my Husqvarna 120i when I bought it a couple years and recently installed it. Today I grabbed the box to order another and noticed the box said it was a chain type H38 / Pitch 3/8" / Link 52 / Gauge .050". but the Husqvarna site says my saw uses H38 / Pitch 3/8" / Link 52 / Gauge .043". I don't know if the saw shop used the wrong box or if I actually got the wrong chain. I'm guessing it wouldn't fit in the bar groove but I don't really know. I used the saw+chain a good bit this week to limb up downed trees and it cut great.
