While at the suppliers sorting out the lighting problem you helped me with I attempted unsuccessfully to find a lockable box for a grid switch, perhaps you may have some suggestions?. What I require is a lockable cover/box to go over a grid switch that measures approx 150mm by 190mm this is so that the switches can only be used by members of staff. Thanks for any help you can give, and please dont think I am being idle,I have looked on the net and spoken to wholesalers.Kind regards Wes
