GN 300.4 zinc die-cast adjustable levers are produced with a clamping area that is linked via a thrust pad to a bearing and a screw. The design is said to double the clamping force by reducing friction. Zero movement on the contact area between the lever and the component greatly reduces any marking. The lever handles are available in a matte black pebbled finish or in colors including orange, red, gray, chrome-plated, silver and uncoated. J.W. Winco, Inc., 800/877-8351.
