An invention is presented that guides plumbers snake cables into and out of snake cable machines, permitting the user to set the direction of snake travel and providing positive control of the snake cable. This invention is made from two single pieces of metal with drilled piston holes, said piston holes containing pistons that control cams grasping the cable, determining the cable movement. The entire guide is controlled with two simple control levers and is self-lubricating. This invention is low-cost, easy to manufacture and maintain, and is substantially less subject to rust and corrosion because of its design.
