USA Harness celebrates milestone

USA Harness celebrated its 20th anniversary in November 2010. Located in East Texas, USA Harness continues to provide innovative wiring harness products for a variety of heavy-duty commercial vehicle applications. Customers include manufacturers of over-the-road trailers, tag and gooseneck trailers, military trailers, and the secure transport industry.

USA Harness was founded in 1990 by Lawrence R Chambly. He has more than 35 years experience in the wiring and harness industry and is a founding member of the Wiring Harness Manufacturers Association. USA Harness has been ISO 9001:2008 certified for manufacturing and design since 2009. USA Harness maintains a complete tool and die making shop for custom tooling and injection molding dies related to harnessing. The shop includes a 3-axis CNC mill for the creation and replication of tooling.

USA Harness obtained a patent in 2001 for the “USA-Plus” harness system. The system is capable of handling up to ten circuits within a modular over-molded harness system. This ability significantly reduces harness costs for military vehicles and specialty trailers with extra options beyond the standard seven circuit design. The enhanced sealing and secondary pin lock feature assures complete engagement of mating plugs and provides the best deterrent to road corrosives that can destroy a wiring system.

Although the US-based company serves primarily the North American continent, USA Harness products have been specified by manufacturers all over the world, including Asia, Africa and South America. Visit the website at
