Embodiments of a vertical pipe handler system (50) and method of its use include a casing tong handling tool (10) connected to a lifting tool (55) having a gripper head (51) and supported by an arm (53) of the vertical pipe handler system. The casing tong connection (33) of the handling tool is located toward the tool's lower end (21) and may be offset in a horizontal direction from the connection (29) to the lifting tool. The casing tong (60) then hangs off-center relative to the lifting tool. The amount of offset may be effective to prevent interference between the gripper head and a tubular being handled by the casing tong.
