Adapter piece T-Nut to Rioned square coupling

With the adapter pieces from T-Nut to square coupling you can put all your 16mm and 20mm square coupling cable tools (e.g. from Rioned & KaRo) on T-Nut drain cleaning cables. Of course you can also connect a square coupling drain cable in front of your T-Nut.

The short, solid connecting pieces are made of steel. Although they restrict the curve mobility somewhat, they are extremely stable due to their design. They are simply pushed onto the side of the T-pin coupling and engage with the locking pin. Now you can attach any tool with square socket to the square coupling at the front end. When coupling, always make sure that the safety bolts engage in the slot provided.
