ABSTRACT:
The tool of the present invention comprises a pair of locking pliers with jaws specifically designed to include a threaded cavity complementing a threaded hanger rod, so that the jaws may be quickly closed and locked to grip the rod and support an object to be hund thereon until a permanent threaded support nut can be threaded on the rod and run up to the support position. In one version of the invention, the threaded cavity is formed in a pair of adapter inserts, so that different pairs of inserts may be interchangeably received and held in the plier jaws, which are thus adapted to grip threaded hanger rods of different size and different threads.
