The Granberg G778-30 Alaskan MKIV is the 30-inch capacity portable lumber-milling jig from the brand’s MKIV series — sized between the 24-inch home/hobby version and the 36-inch professional version. The 30-inch capacity handles bar lengths up to 30 inches, which covers most consumer-grade chainsaws and pro-grade saws under 70cc.
It suits hobbyist mill operators, arborists with smaller commercial chainsaws, and home shop woodworkers processing felled trees into furniture-grade slabs or rough lumber. The all-aluminum jig stays light enough to carry to remote felling sites.
Granberg has manufactured chainsaw mills in Richmond, California since 1955 — the original Alaskan mill brand.
