This simple tool will make adjusting your Triumph, BSA or Norton single or twin cylinder bike clutch pressure plate springs a snap. Works with your favorite ratchet. The slots engage the presure plate spring nuts and allow you to keep tightening as the stud protrudes proud of the nut. Small, simple, and well made in the USA, this tool will last a lifetime. A wonderful replacement for the really annoying-to-use t-handle style tool Triumph OEM # 61-3700.
