ABSTRACT:
An apparatus for holding in place a first casing while a second casing is connected to the first casing, including an annular clamp made up of three segments hingedly fit together to form a ring. The inner surface of each segment includes an insert within a dovetail which creates secure points of contact between the inner surface of the annular clamp and the exterior surface of the casing. The apparatus includes a carrier having two handles and a ring for transporting the annular clamp. The annular clamp can be positioned inside a bowl-shaped housing having a central circular opening adapted for receiving the annular clamp. An adapter plate can be used for retrofitting the apparatus to rigs of all makes and models.
