| CLEBU11750 Bucking Unit - Type III
APPLICATION: The CLINCHER® TYPE III Bucking Unit is the premiere bucking unit specifically designed to make and break premium thread connections on all oil country tubular goods. The unit minimizes the radial load on the tube to prevent deformation while allowing maximum torque for the connection requirements. The CLINCHER® Type III Bucking Unit is a gear driven unit which allows closer tong and backup spacing. Minimum tong die center to backup die center distance is 11". Additionally this unit is capable of a 4" offset, allowing the operator to make up differing O.D.s on offset tools.
