About Us

A & J Manufacturing Company, (A & J), is a small woman-owned California Corporation that was founded in 1953. We design and manufacture both Commercial-Off-The Shelf (COTS) and Customized equipment racks and enclosures, as well as a variety of associated Installation Kits and Accessories. We occupy a 45,190 sq ft. facility in Foothill Ranch, CA, which houses fabrication and assembly operations, as well as engineering, quality assurance, contracts, purchasing, and other administrative functions. We have established a network of manufacturing representatives that cover the Northeast, Washington D.C., the Southeast, the Midwest, and the South/Southwest.

During our 50+ years of operation, we have designed and developed aluminum extrusions and a unique method of all-bolted-together construction, thereby eliminating the need for welding. A family of extrusions was developed to accommodate a wide range of requirements, from light to heavy-duty enclosures. These extrusions and method of construction are confidential trade secrets proprietary to A & J . They were developed solely with private funds and are provided to the U.S Government, its contractors, and other customers on a “Limited Rights” basis.

A & J environmental enclosures are designed to meet the needs of U.S. Department of Defense and the final products reflect the utmost in simplicity and dimensional flexibility due to the modular design approach. They are easy to install, maintain, disassemble and reassemble when required. A & J builds the highest strength to weight ratio cabinets on the market that meets stringent requirements of military Shock (MIL-S-901) and Vibration (MIL-STD-167-1) requirements, as well as meeting the Electronic Industry Standard for Equipment Mounting (RS-310) and shielding to meet MIL-STD-461 EMI/RFI.
