Protective plug for the towbar
Protective plugs used to be obligatory for towbars, those plugs used to be important parts of the towbar and prevented the pollution of the housing when the detachable towbar had been removed.
In the course of a product innovation of our detachable towbar the housing H2 has been redeveloped. Housing H2 is responsible for the automatic locking device when fitting. Most characterizing for the housig H2 is that no protective plug is needed anymore. On the contrary, a protective plug would only promote the accumulation of dirt in the housing. Hence, the locking device would be disrupted.
How to recognize whether a protective plug is needed or not
If a protective plug is needed, a note will be published in the assembly instructions. All parts needed for your towbar are listed there. If no protective plug is listed there, none is needed for your towbar. Also, this can be seen in the operating instructions for the system 2020 and 2040 marked with a red cross.
