ABSTRACT:
A C-frame composed of a base section having a first jaw extending from one end thereof and a second jaw extending from the opposite end thereof to define a jaw opening. The free end of the first jaw is provided with a first clamp pad affixed thereto facing the jaw opening. An elongate pressure screw is threadedly mounted in the free end of the second jaw and is movable upon threaded rotation relative the second jaw towards and away from the first clamp pad. A polygonal head member having two parallel sides is formed at one end of the pressure screw. An elongate extruded handle having a channel-shaped cross section slidably receives the head member, the parallel sides of the head member being in sliding surface engagement with the inner walls of the handle member. The handle ends are formed to retain the handle on the head member. A swivel ball is formed at the opposite end of the pressure screw. A second clamp pad formed of an extruded member having an arcuate cross-section dimensionally corresponding to the swivel ball diameter, slidably receives the swivel ball. The sides of the extruded member are pinched on either side of the swivel ball to retain the ball between the pinched areas in swiveling relation to the extruded member.
