Have I bought this outlet because I realtiv a Low-bulk surface socket was needed in the heating distributor. Unfortunately, the first installation was just below the return valve for venting, so I had the can implement again. But then was already over the screw. Can say that I know how tight you can put a screw to, but does not believe her. Same down broken the whole box with the pliers and put a new can of Busch & Hunter. Although cheap, but not stable. If it is really mounted only once, then passts. Why but still 2 star deduction, because the screw so the meaning would have put the can and / or can rewire.
