Adjustable cam levers can perform a quick and fine clamping. The adjustment by means of the knurled nut allows applying the best clamping force on the lever. In the meantime, it allows positioning the lever in any desired direction. For this reason, adjustable cam levers are suitable when the turning angle is limited owing to lack of space. The slightly arched shape of the lever and the ergonomic terminal enlargement give the operator a comfortable and safe grip and make the design of the lever more elegant. Glass-fiber reinforced technopolymer lever body and base, zinc-plated steel pin and stud. Assembly: tapped hole or threaded stud.
