In my living room I have skirting boards made of solid material
but had to lay an aerial cable and speaker cable.
First I had the cables attached to the skirting board with Scotch tape.
But that was not the optimal solution thus I constructed the cable clamp.

The cable clamp is fastened by the lower part between the wall and the
skirting board. A column spreads of 0.6 mm may be present between
the wall and the skirting board.
The cable clamp is optimized for skirting boards with a width from min 14 mm.
