A rod and casing handler according to embodiments of the present disclosure includes a boom mount that is configured to be coupled to a boom. A clamp mounting structure is coupled to the boom mount and has a central portion, a first arm, and a second arm, where each arm extends from the central portion. A first clamp is coupled to the first arm and includes a first set of actuatable tongs and a first removable saddle plate. A second clamp is coupled to the second arm, and it includes a second set of actuatable tongs and a second removable saddle plate. The first removable saddle plate has a first arcuate surface sized and shaped to correspond to a cylindrical body having a first diameter, and the second saddle plate has a second arcuate surface sized and shaped to correspond to a cylindrical body having a second diameter.
