The DM55 is used for 2-inch to 10-inch diameter main lines; industrial, commercial, residential, floor drains; grease and roots.  The popular DM55 features a continuous weld frame constructed of an aluminum alloy that is as strong as steel. This sled design allows for service technicians to operate the machine in either a vertical or horizontal position. This machine features electrical wiring that runs through the frame to help protect the operator. The winch hook on the frame makes it easy to lift the machine with a loading ramp or crane.
