The Ratchet-Rod Kit replaces the original threaded rod and nut of the bandsaw with an ACME-threaded rod and nut, for easy rotation, and includes a contoured ratcheting knob for quick and comfortable rotation. Inside the knob is a ratchet mechanism with a tiny flip lever that reverses the drive direction just like a socket wrench. Once the rod and nut are installed, tightening or loosening your blade is quick and easy. Even more ingenious, you can pop off the knob and snap on a 3/8” drive torque wrench to check your blade tension right off the torque wrench, which gives you repeatable blade tension results every time.
