ABSTRACT:
A supporting assembly for energized tubing includes an elevated body having a top post section to which is mounted a rotary head having a clamp member base defining a longitudinal axis. A pair of lock arms project upwardly and are axially spaced apart to form a clearance therebetween which extends transversely of the base longitudinal axis. Position control elements on the head and elevated body cooperate to restrict arcuate displacement of the head to and between locked and unlocked positions disposed substantially 90 degrees apart. In the unlocked position, a tubing length may be inserted in the transverse clearance between the lock arms, following which, turning the head approximately a quarter turn swings the lock arms into engagement with the tubing with the position control elements serving to maintain an arcuate biasing force upon the head and lock arms in order to accommodate tubing of various diameters in a positive gripping manner. Associated cables are also captively retianed by placement within a cable hanger extending from the elevated body and when the rotary head is moved to the locked position, a radial keeper on the head overlies the cable hanger.
