The bow shaped members are spread apart by a threaded spreading member (34) to firmly clamp opposed side walls of the frame member between the head of the bolt, the nut, and the outer surfaces (20) of the pulling clamp. In one embodiment a second elongated slot (90) is provided inwardly of the first elongated slot (28) so that box sections of smaller width may be engaged by passing a bolt through a second set of elongated slots.
