Abstract
A tool for bending conduit comprises a body that has a bottom shoe portion which is curved along its length and in which there is a downwardly opening groove that is symmetrical across its width to a plane of symmetry, a tubular handle supporting socket projecting up from the shoe with its axis in said plane, and a hook portion in front of the shoe. Integral ridges on the body define sighting lines contained in a plane parallel to said plane of symmetry, each such line designating attainment of a predetermined bend angle when it is perpendicular to a supporting surface. The ridges define upper line segments on the socket that diverge downwardly from a point on the axis about which the shoe is lengthwise curved and lower line segments on the shoe that are lengthwise aligned with respective upper line segments.
