"Great little box. very nice quality, reasonable price. nice big cutouts that popout easily with a blade leaving no nasty edges.
Only 1 small warning. The lugs that stop the box coming out of the wall after fixing, stop 6mm short of the top of the box. This means that if your pasterboard or hardboard wall is less than 6mm thick you will have slack movement where you can pull the box out of the wall slightly after fixing!
To avoid this use small packers for thinner walls either side of the box on the inside of the wall to make up the difference so the fixing lugs have somthing to bite on.
All their boxes appear to have this 6mm limit which is daft, 2 more mil and you could use on any wall asis!
"Bought two of these to move some sockets, 45mm is probably best for electrical outlets as there Is more room for wiring behind the socket but 35mm was great for a TV outlet, clipped into the cut plasterboard with no problems."
