Abstract: An offset conduit bender has a pair of shoes which are pivotally connected to one another so that axes of the shoes remain parallel. Each shoe has a specially shaped groove in it for receiving a tube inserted into the grooves and which support the tube as the tube is bent. The grooves also have straight sections for quickly inserting a tube into the grooves from the side of the grooves. The amount of offset is accurately adjustable by a stop which is provided beneath the movable one of the shoes and the axial position of the offset relative to one end of the tube is accurately adjusted by another tube end stop. In addition, inner and outer tube deburring tools can be provided on the bender, and the bender is preferably mounted on a portable cart.
