Use the DM138 for 1-1/4-inch to 3-inch residential lines, sinks, shower and bathtub drains. The DM138’s continuously welded frame holds up to the challenges of the job, and a heavy-duty front bearing mount also adds to the stability of this machine. The machine is equipped with a self-aligning head bearing which ensures that the reel will stay in place when in operation. It also allows for a quick reel change on the job. The DM138 machine’s guide tube keeps surfaces from scratching while you are running cable. This small machine can also operate in an upright position to allow running cable easier. Non-marring rubber pads protect flooring whether the machine is run in a horizontal or vertical position.
