Abstract: The present disclosure is directed to systems and methods for simultaneously and concentrically handling cylindrical objects of different diameters. Also, the present disclosure is directed to a handler having a clamp that includes pairs of outer and inner tongs spaced apart on separate sides of the central plane that is orthogonal to a central longitudinal axis of the cylindrical object. Some embodiments may include a clamp having a mounting plate and a piston assembly coupled to the mounting plate where the central plane is parallel to the mounting plate. Some embodiments include a plurality of linkage bars pivotally coupled between the piston assembly and the plurality of outer tongs and inner tongs. In some embodiments, in response to a movement of the piston assembly, the inner and outer tongs pivot between an open position and a closed position to secure the cylindrical object between the inner and outer tongs.
