Chain knocker for 20mm Rioned Master drain cables for drain cleaning

The chain knocker is one of the important drain cable tools. It is used to remove incrustations and deposits on the pipe walls. Due to its design it is very flexible. Due to the rotation of the tool, the chains are tensioned and lie against the pipe wall. The chains thus attack the deposits and remove them effectively.

The chain knocker is available with 2 chains with spikes, with 4 chains with spikes, with 2 plain chains or 3 plain chains. It can be connected to 20mm drain cleaning cables of the Rioned Master. Its length is always 160mm and it is made of stainless steel. The chain knocker weighs between 250g and 300g depending on the model.

This tool from E&R is compatible with the Rioned chain knockers (2 cam chains) and 125610 (4 cam chains).
