Chain knocker for 13mm & 16mm Rioned Allround drain cables

The chain knockers are one of the important drain cable tools. They are used to remove incrustations and deposits on the drain walls. Due to its construction it is very flexible in curves. The rotation of the tool causes the chains to tighten and lie against the pipe wall. The smooth and cam chains thus attack the deposits and remove them effectively.

The chain knocker is available with 2, 3 or 4 smooth chains or with 2, 3 or 4 cam chains. It can be connected to 13mm or 16mm drain cleaning cables with 3/8" square coupling, i.e. to the Rioned Allround. Its length is 160mm and it is made of stainless steel. The chain knockers weigh between 200g and 250g depending on the model.

This tool from E&R is compatible with the KaRo chain knocker 117906 (2 smooth chains), 117911 (4 smooth chains), 117905 (2 cam chains) and 117910 (4 cam chains).
