Abstract: A tool for attachment to a working end of an excavator arm for use in supporting a pipe section while lowering it into a trench. The tool has a proximal end from which extends an elongated arm, held in an approximately horizontal position when in use. A vertical riser is attached to the arm at the proximal end, and an upper end of the riser is attached to a quick coupling connector for attachment to a corresponding mating quick coupling on the working end of an excavator arm. A lateral support, extending from each side of the tool is included, making the tool self supporting in a vertical position on level ground in a position ready for connection to an excavator arm. A further embodiment includes the combination of the tool as described above with a leveling device attached to an excavator, a combination that provides precision alignment and joining of pipe lengths in a trench.
