More and more I see sockets without the cover caps over holding screws. I think they look terrible without because of the design of hole. Just looks like they are missing.
Why use that type if your not going to fit caps?
Opinions
The reasons I do not use the screw caps are thus:-
1) Sometimes a plasterer has decided that to fill the chases round my boxes are not in his price, and cannot possibly offer the customer to fill them in. So I can't fit the caps successfully.
2) The painter hasn't mistcoated or painted yet, and he wants to pint behind the accessories.
So I can't fit the caps because I know he will struggle to loosen off the accessories.
3) The tiler has not yet tiled the kitchen.
So I can't fit the caps because I know he will wreck the accessories trying to the get the caps off.
4) I may need to inspect the wiring behind some of the accessories, I don't want to pi55 about with screw caps.
5) Some of the older accessories in the property do not and never have had screw caps, so fitting screw caps on the new stuff just makes it more obvious that things don't quite match.
6) If I fit screw caps everywhere, someone may loosen an accessory, and lose the screw caps - leaving my installation looking inconsistent, because some accessories will have screw caps, and some won't.
7) Sometimes they don't fit very well, and fall out, leaving an accessory with one screw cap only.
8) If they fall out, it's something a minor could swallow or stick up their nose.
