ReceptXtenders ProBox (39) 3/8" Single Gang Outlet Box Extender

UL Listed Receptacle Outlet Extender — Made in USA

The ReceptXtenders 3/8" Single Gang Outlet Extender is built for situations where a standard 1/4" extender just isn't enough. When drywall is thicker or the outlet box sits deeper, this is the professional's go-to fix — bringing single-gang outlets perfectly flush without any guesswork. The ProBox is a compact, organized bulk supply for electricians, contractors, service vans, maintenance shops, and store shelves.
