"Good quality again from MK with this 16mm pattress box. Nice slim design my reason for purchase. As it is a tight fit to the rear it's worth bearing in mind that it can be a little more difficult to fit than normal and also that cable exit is the the rear only no side exit knockouts. To be fair this is impossible really anyway as the fit is so tight. I got around this by fitting the cable into the wall to the rear and then out to the side so the socket was still mounted flush to the wall."
