An apparatus that attaches to the end of the electrical fish tape to eliminate or reduce drag and friction while the fish tape is pushed through bends in electrical pipe with a roller attached to the end of an electrical fish tape or snake to drastically reduce friction and drag when the fish tape or snake is being pushed through bends in electrical pipe. The roller is designed to rotate when coming into contact with the inner pipe wall at any position. Inner bearing further magnifies roll, takes advantage of the flat side of the fish tape to position the roller going into and through the bend for optimum roll.
