They are made of hardened steel, compared to chain knockers in simple version these professional tools have less wear and tear, which means more cleaning power. We recommend the use of smooth chains for cast iron and plastic pipes.

Chain kockers are an indispensable tool for every end pipe cleaning in pipes. When working, the centrifugal forces cause the chains to lie against the pipe wall and remove deposits quickly and effectively.
