Chain knocker "extra flexible" with 22mm T-Nut (7/8") from rak

The rak chain knocker in sanitary version is an extremely flexible drain cable tool. With a length of 170mm it is considerably shorter than the standard rak chain spinner with 220mm length. In order to make it even more bendable, the spiral core of this chain knocker is wide wound. It is therefore more flexible than, for example, the corresponding model from ROWO.

The chains are available as smooth chains and as chains with spikes. The chain knocker 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. As the chains are not hardened as in the standard version of rak, the chain knockeringer should be used mainly in the sanitary sector, where blockages often occur due to grease, saponification and lighter deposits. It should also always be used for the final cleaning of the pipe after extensive pipe cleaning. The chain slinger chain knockers generally only be used with reinforced drain cleaning cables.

This rak chain knocker in sanitary version for 22mm drain cleaning cables is available with 2, 3 or 4 smooth chains or cam chains (with spikes). The coupling is a bevelled 22mm T-Nut coupling for connection to 22mm drain cleaning cables. The chain knocker is thus compatible with all T-Nut systems from ROWO, ROTHENBERGER, RIS, REMS, RIDGID, Rioned Victor, etc.
