Chain knocker "flexible" with 10mm core, 16mm T-slot for drain cleaning

The chain knocker is one of the most important drain cable tools of all. This version for 16mm drain cables has a 10mm thick spiral core and is kept flexible to allow for improved bow mobility. The chain knocker is available with different chains and can therefore be used for different purposes. Smooth chains are suitable for PVC and clay pipes, chains with spikes for steel, cast iron and concrete pipes. By rotating the chain knocker over the drain cleaning cable, the chains throw themselves outwards onto the wall and remove incrustations, deposits, grease and other drain blockage. It should also always be used for final cleaning of the pipe after an extensive drain cleaning.

The chain knocker for 16mm drain cleaning cables with 10mm core is available with 2 or 4 smooth chains or 2 or 4 cam chains (with spikes). The coupling is a beveled 16mm T-Nut coupling for connection to 16mm drain cleaning cables. The chain knocker from rak is therefore compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, VIRAX, RIS, REMS, RIDGID, Rioned Victor , etc.
