I need to change the electric distribution setup at home, but I dont want to go with in wall wiring. Could only find aircooling duct (*) at them hardware stores or ridiculously small apparent electric ducts.
Does it even exist in here or will I have again to order stuff from china ?
(*) can't use that, ther is no 3 way pieces when you need to go left and right in a room or at the junction of some corridors...
