The 25 ft Electric Sewer Auger is capable of clearing clogged sink, tub and laundry cleaning drain lines through 3” in diameter. Just pull the Grip Shield back to engage the cable – slide it forward to release. It’s safer than a spinning chuck and it automatically adjusts for different cable diameters. As a result, you get your cable into the line faster, pull it out faster, and have full control at all times.
