Abstract
A plastic drain auger made from plastic, such as polypropylene or polybutylene, extruded to provide an elongated member having an outward appearance similar to a helical coil. Extrusion of the plastic produces a structure having improved torsional and tensile strength which is essential so the auger can withstand fairly severe forces created as it is pushed and pulled through a drain pipe. The use of a helical coil form for the auger provides the flexibility necessary for the auger to be rotated, twisted and contorted within a drain pipe system.
