Abstract: A mounting apparatus is disclosed for securing and maneuvering an elongate tubing of general cross-section which permits longitudinal movement through the apparatus but inhibits lateral movement or vertical movement. The apparatus includes a channel for the tubing and two pair of opposed jaws which cooperate to limit the motion of a tubing held therein, and each jaw is provided a roller which permits the tubing to slide longitudinally through the apparatus while preventing lateral movement. The opposed jaws are mounted so as to open and close symmetrically about a centerline of the channel and the closing of the two pair of opposing jaws precisely centers the tubing on the centerline. The apparatus is rotatable, and is used in combination with a drive support unit to permit movement between the elongate tubing and an operation station for automated operation along the length of the tubing.
