A compact guide (1) for introducing multiple bends in at least one plane in a pipe (14), conduit, or other tube-like item. The guide (1) has a gauge section (2) rotatably attached to a mounting section (3) and is affixable by means of a non-deforming clamp (4) to the end of a pipe segment to be bent. The gauge section (2) has a bend-angle gauge and a bend-plane level. The bend-angle gauge is a plumb arm (5) mounted so as to measure and indicate th e bending of a pipe (14) to any degree of bend. The bend-plane guide is a 360 level (16) mounted on an upper face of the plu mb arm (5). Multiple bends are made in the pipe segment without removing or re-aligning the guide (1). This ensures that the initial reference position is maintained throughout the bending process and ensures that all bends are in the proper bend-plane, thu s avoiding "dogging" between successive bends. Multiple successive bend-planes also may be established without removing or re-aligni ng the guide (1) on the pipe (14), by rotating the gauge section (2) of the guide relative to the mounting section (3) by the magnitu de of the desired out-of-plane angle.
