Over half a century ago, a pipe and fitting specialist noticed that too many field workers were sustaining injuries while trying to force open stubborn valves in hard-to-reach areas. His innovative solution was a chain wheel that he called the “Roto Hammer”, a product which harnessed the principle of a hammer striking an anvil to safely open and close stuck or “frozen” valves in a manner that protected the operator from injury.
