Hello Sih109, The installation boxes are all built to standard dimensions, so you don't need to stick to LAP boxes for LAP sockets. We stock a range of other brands, but the surface boxes like this are all white plastic. We do stock galvanized steel installation boxes as well, have a look at our code 88287, although these would generally be installed in the wall. Or for a tougher surface mounted system you could consider the metal clad socket range, something like 69127. Thanks for using Q&A
