These 10" steel ProKleen Starter Rods are ideal for use with a 1/2" electric drill with tools to break out clay flue tiles or to remove creosote with a chain type tool. They are 1/4" in diameter and have the Torque Lock Connector (TLC) design, that has an easy to use quick connect coupling. The time saving TLC connection eliminates the need for multiple adapters and the button is recessed to avoid unexpected disconnects. This is an all-in-one system that can be used with most brushes, rods and tools. These rods can be rotated in either direction without separation.
