Gorlitz's heavy duty power cable feeder and puller T 01A is recommended to be installed on our sewer & drain cleaning models GO 50 Series. Our feeder incorporates various improvements in power, speed and construction. The drive pins, U-brackets, spring pressure pad and heavy duty knob assembly spindle and plate are heat-treated for extended life and longer wear. Most important, all aluminum housings are provided with grease fittings to lubricate the pistons. Our power feeders will advance or retract left or right hand coiled cables from 3/8" to 1/2" in diameter at a rate from 0 to 32 feet per minute depending on machine revolution.
