ABSTRACT:
The conduit bending tool of this invention has on its body a pair of pads which are spaced apart in the direction lengthwise of the arcuate bending shoe and which define recesses that open to one side of the body wherein end portions of a straight cylindrical spirit level vial are closely receivable. Cement on a surface of each recess that embraces the vial partway around it secures the vial in place. The pads and recesses are defined by one of the two main mold elements that form the body, which have their parting place on a plane of symmetry in the body, and the vial is installed by simply inserting it into the recesses.
