Because of their superior flexibility, the 5' x 7/8" ProFlex Rod is the tool of choice for cleaning from below and when going through 45° bends, offsets, breeches or thimbles. They can be maneuvered where others fail to reach. ProFlex heavy duty polypropylene rods have rust-proof fittings that are flush with the rod, eliminating hang-ups on flue tiles. This rod comes with 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.
