ABSTRACT:
A hand bender tool for bending tubes, pipes, conduits and other tubular material, and which is provided with raised indicators on a bending shoe and handle socket that coact with a conical sighting indicator disposed in a position above the shoe, to allow an operator to accurately bend a pipe to a desired angle of bend. A contoured foot treadle is provided with serrations which prevent slippage of the foot of an operator during a bending operation, so as to permit the operator to employ leg power to the fullest advantage.
