Therefore, before Stroebe, Stroebe well thought out direction, to the extent possible, reduce their length, at the same time, do not forget that all should go Stroebe strictly at right angles. This is a professional, and beautiful, and most importantly, to see and where does the wire protruding from the walls (less likely to kill or to drill him.) And even if you plan to line the walls with plaster or plasterboard, or make false ceilings then you probably do not have to do quite Stroebe, or at least its volume significantly decreased.
In order to do extra work, plan to which wires go, be sure to make a drawing. For example, if you have one wall, not the carrier, with both sides of the socket, making one side of the wall Stroebe, and to exit on the other side of the drill hole. As a result, we've got only one Stroebe on two sides of the wall. Also proceed with a skylight for chandeliers, etc.
To Stroebe needed punch the wall, whose power depends on the strength of the walls, you also need to Bulgarian diamond disc. If conditions permit, that is, the apartment is not living, etc., will soon, if all the planned propylene Stroebe grinder with a diamond disk, and then the remaining hollow drill. But with this method produced a lot of dust and carry it is recommended that all protective equipment (respirator, goggles, gloves, headphones). If conditions do not, or you do not like large amounts of dust can be the same storage work done alone puncher, but it is more severe and long version.
For recessed under Escutcheon, requires a special crown. If epolzovatsya crown, draw dimensions Escutcheon on the wall, drill drills on the perimeter and inside the hole layout, with a depth slightly greater than the depth Escutcheon, set the drill in position and just slotting a special shovel inside hollowed out all unnecessary marks. Best of luck.
