An economical, compact guide for introducing multiple bends in one or more planes in a pipe, conduit, or other tube-like item. The guide has a gauge section rotatably attached to a mounting section and is affixable by means of a non-deforming clamp to the end of a pipe segment to be bent. The gauge section has a bend-angle gauge and a bend-plane level. The bend-angle gauge is a plumb arm mounted so as to measure and indicate the bending of a pipe to any degree of bend. The bend-plane guide is a 360° level mounted on an upper face of the plumb arm. Multiple bends are made in the pipe segment without removing or re-aligning the guide. This ensures that the initial reference position is maintained throughout the bending process and ensures that all bends are in the proper bend-plane, thus avoiding "dogging" between successive bends. Multiple successive bend-planes also may be established without removing or re-aligning the guide on the pipe, by rotating the gauge section of the guide relative to the mounting section by the magnitude of the desired out-of-plane angle.
