January 14, 2013
GMS Distribution’s G-Unit enables professionals to use 240-volt dryer and range circuits for 120-volt fans and dehumidifiers. The unit plugs into an existing range or dryer 240-volt electrical receptacle and converts it into four, 120-volt receptacles. The unit comes in a rugged case for easy portability and storage.
