Abstract: An improved bar clamp in which the first jaw assembly consists of a handle assembly or setting unit, on a slide bar inside of an independently mounted first jaw. A finger lever is pivotably attached to the setting unit and at its upper end pivotably attached to the first jaw. A braking lever is included in the first jaw, and a driving lever in the setting unit.
