ABSTRACT:
For bending wiring conduits projecting up from the floor of a building under construction, the present apparatus has a padded block providing a lower abutment, a grooved block providing an upper abutment located above and behind the lower abutment, and a jaw pivotally movable from a retracted position on the opposite side of the conduits from the lower and upper abutments to an extended position toward the upper abutment to force the conduits against the padded block for forming lower bends in the conduits. The jaw has a grooved convex face which engages the conduits to form upper bends of the opposite curvature in the conduits between the lower and upper abutments. The padded block is adjustable to determine the amount the conduits are bent. The grooves in the convex face of the jaw are laterally spaced to spread the conduits apart laterally from their spacing at the floor. A manually pivoted handle actuates the jaw through a mechanical linkage.
