Oregon tool to measure all your saw chain specifications, bar gauge and file sizes for your saw.

This is the nicest all in one tool we have used to date for identifying chains.

The Oregon part # is 556418 and the old part # is 110185.

Check the pitch (distance between rivets) by holding it up to the side rivets.
Check the gauge of the chain by slipping the drive-link into the slot.
Check the gauge of your bar by inserting and matching one of the corner tabs.
Check the size of your file by inserting it into the best fitting hole.
