摘要： A plastic conduit bender comprises an integrally molded handle and head portion. A steel hook reinforcement is molded directly into the head portion to provide sufficient force for bending the conduit. Steel reinforcements can also be provided in a grip region of the handle. A plurality of vertical sight lines, indicating bend angles, are provided from an apex molded into the handle and extending to an arcuate shoe portion, allowing the user to gauge the approximate bend angle. A flat surface including rounded saddle portions for receiving the conduit is positioned on the handle to allow the conduit to be bent back or straightened, the rounded saddle contact surfaces preventing damage to the conduit as it is bent back.
