The Assembly has made with me for a little headache. At least I did not understand the instructions provided at the time immediately. Really it was not self-explanatory.

PS:
The holder can be used further elsewhere in other respects. Replacement adapters are sold here at Amazon: WENKO Replacement Set Power-Loc. And the glue you also get separately: WENKO Power-Loc adhesive.
