Wall Plates
 

I'm looking for an oversized (or as large as possible) single gang wall plate. All of the big box stores I've gone to so far basically only carry standard and "large," with no option of special ordering anything bigger. Anyone have suggestions of shops to check out or reputable websites I can order from?

Any electrical wholesaler should be able to get you this.

IE:
Nedco
Wesco
Eecol
Torbram
Westburne

to add to that list
EB Horsman
Guillevin

and if you know the model/make you can actually take a look and see if they're available on amazon if you do not have access to wholesalers
