General Pipe Cleaners’ Double U-Cutter and Double Heavy-Duty Side Cutter, both nicknamed “The Spider,” feature both front and rear blades. Cutting starts as the cable feeds into the drain line and continues as it retracts. Each comes in 3” and 4” sizes. The Double U-Cutters also can be adapted to sectional machines or to other brands of cable-type drain cleaners. Drain clog cutter
