I have a client that insists on having 2 4-gang switches stacked on his back patio for a plethora of outdoor lighting. I've never seen a 4-gang water tight cover but recently in Maui I saw a large hinged cover that would work. It was on a commercial site but was being used exactly the way I intend. It looks like an outdoor bubble cover except it was probably 1' X 2'. The part that went against the wall had the neoprene type of seal built onto it and it fastened against the building with screws.
Any ideas who has one of these?
