Extended Handling May Be Required
  • Chain Knocker Cleans 4" Drains
  • Carbide Grit Head Penetrates Tough Blockages
  • Removes Wipes, Grease, Soft Blockages, Scale and Roots
  • Chain knockers expand to the size of the pipe
  • Nylon/Steel Brushes - 50% Nylon and 50% Steel Brushes can be used for light grinding of pipe walls and to help clear debris sitting at the bottom of a pipe. These brushes can also be used for relining applications such as preparing PVC walls for a liner.
  • Ball and Drop Heads - Penetrating heads only that can be attached with standard chain knockers or brushes when carbide tipped chains are too aggressive. Ball heads designed for optimal in pipe negotation in smaller lines and drop heads designed to navigate down stacks in back to back applications.
  • FlexShaft Sandpaper Blades - FlexShaft sandpaper blades are a great tool to aid in pipe rehab jobs. The sandpaper attachments can be used to prep pipe before CIPP patching or relining, to smooth transition edges after a reinstatement, and as a finishing tool when descaling or milling.
