Ruland LF30-CL-M4:12-ZS is an adjustable clamping lever with a 30mm long flat handle, M4 threaded stud, 12mm stud length, 12mm sleeve, and 32mm overall height. The threaded stud is designed to replace standard M4x12 hardware in Ruland one- and two-piece shaft collars. Once installed on the shaft collar, the lever is turned until the user reaches their desired torque. It does not require any tools to install, making it ideal for applications that require frequent setup changes and adjustments. LF30-CL-M4:12-ZS is black to seamlessly integrate with the aesthetics of most equipment. It is manufactured by Otto Ganter, stocked by Ruland, and RoHS3 and REACH compliant.
