3rd Generation
Family Business

Founded in Denver in 1978 — minority-owned, three generations deep, still privately held. We've grown into one of the country's leading designers and manufacturers of specialized equipment enclosures, but the same family that put our name on the door is still putting it on every building we ship.

DBE & MBE certified across multiple states. 350+ combined years of in-house expertise. Every enclosure we build, we'd be proud to put our name on. Because we do.
