J.W. Winco's metric-sized Heavy Duty Push-Pull Toggle Clamps convert the circular movement of the handle into straight-line action of the clamp along its axis. The lever arm is constructed of case-hardened sheet metal steel with a red plastic hand grip. The rod is copper-plated steel, and the base is nickel-plated brass with a black lacquered finish. The clamps are available in two sizes with either clockwise or counter-clockwise turn.
