GMS Distribution manufactures and sells portable power distribution boxes and electrical cords for contractor use (residential, apartment and hotel). Our primary goal is to save our customers (contractors) time and money by providing the industry with an easy source of electricity for their equipment. Designed by an electrician, GMS’s Portable Power Distribution Centers (the “G-Unit”) are small, compact, lightweight, colorful and easy to use. Every G-Unit is hand-assembled by GMS Distribution in the U.S.A. to provide you with a simple power solution that will exceed your expectations. Headquartered in Fort Wayne, Indiana, GMS Distribution distributes and sells its products in the United States and Canada.


GMS Distribution was founded in 2008 by President, Gerrett Stier, a former journeyman electrician and current industry expert on electric solutions. GMS Distribution designed its first power box as a response to the industry’s request for more electricity. Because of his years of experience as an electrician, Gerrett knew where a large amount of untapped electricity could be found and embarked on a path to create such a product and the necessary adapters and cords.

Through a series of prototypes and product enhancements in 2008 and 2009, GMS refined its power box from an initial metal box with hand-made adapters to an insulated plastic box with molded adapters. In 2010, GMS passed all UL’s safety and durability tests and released the current “G-Unit”, now available in the colors yellow, blue, green, black and red, with a variety of adapter options. The G-Unit is C-UL-US Listed, making it the perfect temporary power source for American and Canadian contractors (residential, apartment and hotel).
