发明名称 Offset pipe bending device
摘要 An improvement in a pipe bending device to predetermine the offset distance without removing the pipe from the bender. An adhesive tape with incremental markings thereon is applied on the handle of the pipe bender in a manner so that a sight line intersects the handle at the incremental mark indicating the amount of offset desired after the first bend is made.
