Offered here is a New Chuck Release Lever for a Sioux Model 680 Valve Grinder. The Sioux Part Number is 54319. The knob is not included. The new one is pictured next to an original as a reference. The new one without the red knob is the one you'll receive. These levers tend to get loose where they thread into the chuck and eventually can damage the threads in the chuck.
