Ruland LV-MCL-11-SS is a one-piece quick clamping shaft collar with clamping lever with a 11mm bore, 28mm OD, and 11mm width. It is made from MCL-11-SS and LF30-CL-M4:12-ZS. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. The threaded stud on the lever is used in place of standard collar hardware. When combined, the two parts create a shaft collar that requires no tools to install, remove, or reposition and is ideally suited for packaging, printing, and other applications where frequent setup changes and adjustments are needed. Once the lever is installed in the shaft collar, users simply turn the lever until they meet their desired torque. The adjustable lever can be reposition by the user without the loss of holding power by lifting the handle and twisting it 40° to lock it in a new position. This allows for use in space constrained environments where 360° rotation is not possible to fully seat the lever. MCL-11-SS is made from 303 stainless steel. LF30-CL-M4:12-ZS has a zinc plated steel handle and stainless steel threaded stud. This material combination allows for a durable quick clamping and release component with high corrosion resistance that is suitable for most industrial applications. The lever is black to seamlessly integrate with the aesthetics of most equipment. MCL-11-SS is manufactured by Ruland and LF30-CL-M4:12-ZS is manufactured by Otto Ganter. LV-MCL-11-SS is RoHS3 and REACH compliant.
