Weve miniaturized our big machine power cable feed and put it on the Super-Vee to give you feeding speed and convenience you havent seen before in a hand-held power drain cleaner. In tight or awkward places, the Power-Vee is like having an extra hand. To feed the cable just start the Power-Vee and squeeze the feed lever; to retract it, reverse the motor and squeeze the lever. The feed handles 1/4, 5/16 and 3/8 cables. No adjustment, disassembly or additional parts required. Our Dyna-Thrust bearing system helps carry the weight of the drum, significantly reducing wear on the motor shaft bearing and extending the life of the tool. Also adding to the Power-Vees durability is the heavy-gauge stamped aluminum drum. Of course the cables are Flexicore with an integral wire rope center. Nobody makes cables like General.For sinks, tubs and laundry drains,Power cable feed drives and retrieves cable at up to 16 ft./min,Automatically adjusts to different cable diameters,Quick-change cartridge makes switching cables clean and easy,Unique dyna-thrust bearing system for longer tool life,Flexicore wire rope center cables have unequalled strength yet the right amount of flexibility
