ABSTRACT:
A rod bending device includes an L-shaped bracket formed by a mounting plate adjoined to a support plate at a substantially 90.degree. angle. The bracket is mounted to an outwardly extending corner wall whereby an outer surface of the support plate aligns with one of the intersecting corner walls. A bending assembly is mounted to the support plate and includes a pivot support block and corner block which extend outwardly from the support plate and which are spaced from and parallel to one another forming a rod retaining cavity therebetween. The corner block having a corner edge which forms the fulcrum about which the rod is bent. An end block extends between the corner block and the pivot support block to enclose the rod retaining cavity. A gap is formed between an upper portion of the pivot support block and the support plate for receiving a pivot arm. The pivot arm is pivotally secured within the gap. An outer free end of the pivot arm is formed with a rod receiving channel which engages the rod to be bent and retains the rod substantially in line with the pivot arm. The pivot arm has a pivot point which is positioned on a side of the rod receiving cavity opposite that of the fulcrum of the corner block.
