ABSTRACT:
A device for the support of elongate members, such as tubing in a well bore, by a stationary gripping jaw and a movable gripping jaw. The movable gripping jaw is moved by a threaded shaft which pivots about one end into and out of engagement with a partially threaded nut to facilitate rapid movement of the movable gripping jaw relative to the stationary gripping jaw while maintaining the movable gripping jaw substantially vertical at all times. The stationary gripping jaw may be selectively positioned to accommodate a range of selected tubing sizes.
