ABSTRACT:
A locking pliers pulling system for tensioning or hanging a workpiece comprises a set locking pliers to be secured to the workpiece linked to a pulling device via an adapter. The adapter is threaded into the hollow adjustment barrel of a set of locking pliers of the type commonly referred to as Vise Grips.RTM.. The puller adapter is an integral component comprising a threaded, elongated shank portion, coaxial follower portion and a coaxial eye portion. The shank is adapted to screw into the adjustment barrel of the locking pliers. The follower portion extends from a first end of the shank portion to engage the locking link of the pliers, within the adjustment barrel. The eye portion extends from an opposite end of the shank portion to mate with a puller. The puller may be a winch, cable puller of the type commonly referred to as a "come-along", a slide hammer or the like. The eye promotes self centering of the link between the puller to the pliers. The eye may be oval or may define a narrowing slot. A narrowing slot also promotes self securing. An alternative embodiment allows the eye portion to coaxially swivel relative to the shank portion.
