Locking screw to fix electric flush-mounted distribution in walls

摘要

A locking screw to fix an electric flush-mounted distribution in walls can be made selectively out of plastic, since low self-weight. It can be screwed together with a second one of similar construction. By arbitrary repetition of this process, it can be screwed to a threaded bar. It can be screwed in by four screw mountings in the back wall and two to the left and right in the side parts of the distribution box.
