Abstract: A tool for mounting and leveling forming boards to a vertical wall that has three legs parallel to each other. Two of these legs are separated sufficiently to permit a forming board only between them while the third leg is separated a larger distance and typically the distance between two spaced apart forming boards. A puncturing mechanism is mounted to the outer leg of the pair that accepts the forming board so that it can be releasably held. A leveling device is mounted on a transverse member that connects all three legs.
