Established in January of 2001 under the name Tri-County Enclosures, Inc., APX Enclosures began with just 12 employees focusing specifically on the outdoor traffic enclosures market. In late 2003, Tri-County officially changed names to APX Enclosures and began spreading rapidly into other markets including telecommunications, security, and public works. Today APX has tripled its workforce and is recognized for its expertise and cutting-edge solutions as APX continues to grow in the enclosure space.

All of our enclosures are made in the USA!
