Geoff Asked :
We are hoping to buy this for quite a tight situation. We will be using it with the actuation at the front, not at the top. Can you explain what the diagram is showing on the far right? It seems to show the actuation sticking out by 7cm, where we would prefer it to be flush with the wall. Does this mean that the installation's total depth will be 14cm + 7cm (i.e. 21cm)?

Answered By QS Team :
The extra 7cm is for the protection box, which is trimmed down depending upon the board's depth and tiles at the front.
