The length of your chain is determined by counting the number of drive links in your chainYour drive link count has a direct correlation to your bar’s lengthBe careful; a bar made by OREGON may take a different drive link count than that of another producerHere’s a tip: count the number of drive links in the chain you have now, and write that number down someplace where you can find itOr, if you have an OREGON chain in an OREGON box, the drive link count is stamped on the flap; you can save that flap for future reference
