The Ken-Way 400 helps remove roots and other obstructions from sewer and process lines from 3 to 10 inches in diameter. The coned drum allows for maximum torque buildup and can hold 150 feet of 5/8-inch cable, 130 feet of 11/16-inch cable, or 110 feet of 3/4-inch cable. Its small footprint and 8-inch ball-bearing wheels and stair climbers allow it to operate in difficult-to-reach areas. It is available with an optional cable drive for feed and retrieve. Each unit comes with a toolbox containing a set of blades, flexible leader and retriever. It is powered by a 1/2 hp motor with a three-speed pulley. A ground fault interrupter is built into the power cord and the foot switch is air activated. 800/533-0551; www.kenway.com.
