ABSTRACT:
A fork member for the bending section of a pipe bending apparatus includes a flat base having two symmetrically disposed diverging legs. Each leg has a protruding headed pin and a set of slots extending radially from the pin symmetrically on both legs. An elongated arm is removably mountable on each leg. Each arm has two axially elongated keyhole openings and an axially extending rib. When a selected opening in the arm is hooked over a corresponding pin on the corresponding leg, and the rib on the arm is disposed in the selected slot in the leg, pipe abutment members carried by the arms will be suitably spaced and positioned.
