PROUDLY MADE IN THE USA

Authentic American Manufacturing

We're not a faceless corporation or overseas operation. We're real people in a real place, crafting quality wire harnesses in a historic firehouse in Kingston, New York.

“Why do I have to wait multiple days for a simple quote? Haven't we figured out a better way to do this by now?”

The Historic Rondout District

We're based in Kingston's legendary Rondout, once the third-largest port on the Hudson River and a crucial gateway that moved coal from Pennsylvania to New York City via the Delaware & Hudson Canal. This thriving 19th-century maritime district shaped the entire Hudson Valley's industrial legacy.

Our workshop is housed in the historic Union Hose Company building at 218 E Union St, continuing the neighborhood's tradition of American craftsmanship and innovation.
