Chain knocker "ultra flexible" with 8mm core, 16mm T-Nut

The chain knocker is one of the most important drain cable tools at all. This variant for 16mm drain cables has a spiral core of only 8mm thick and is kept extremely bendable to allow for improved bowing. The chain knocker is available with different chains and can thus be used for various purposes. Smooth chains are suitable for PVC and clay pipes, while chains with spikes are suitable for steel, cast iron and concrete pipes. By rotating the chain knocker over the drain cleaning cable the chains throw themselves outward to the wall and eliminate there incrustations, deposits, grease and other drain blockage. It should also always be used finally for final cleaning of the pipeline after an elaborate drain cleaning.

The chain knocker for 16mm drain cleaning cables with 8mm core is available with 2 or 4 plain chains or 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 thus compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, VIRAX, RIS, REMS, RIDGID, Rioned Victor , etc.
