This practice has limitations. Bending rigid conduit or IMC is like fabricating a “double thick” thin wall conduit. D. is larger and the operator must move more than twice the metal to bend it. It follows then, that newly designed benders were needed to bend these heavier conduits to the proper radius. Obviously, existing thin wall benders were not the answer because the grooves did not fit and their radii were too large, resulting in awkward inappropriate looking bends. To safely bend these heavier conduits new tools have been engineered.
The clerk hands you the axe head but informs you that you’ll have to provide your own handle. , a one inch plumber’s pipe “T” fitting was cut away at the side, all sharp edges were then filed down Hand Bender Types Described 55 smooth (like a bell-mouth) and a short length of stiff 1-in. ” This served as a handle lever. It was an improvised tool made up of material found on almost any job. and it stuck. A. , and 3/4”-in. They are engineered to the proper length, reamed and chamfered on the ends, plated or galvanized to prevent rust and corrosion (see Fig.
