A & J Manufacturing Company has specialized in the design and manufacture of customer specified enclosures since 1959. The enclosures have ranged in size and configuration from a small computer card cage to a large multiple bay console and have been designed and tailored to meet the customer’s specified needs.

All of our enclosures are manufactured from 6061-T6 aluminum and are of bolted-together modular construction and meet the requirements of MIL-S-901 Shock and MIL-STD-167-1 Vibration.

With the simplicity of design, no welding, special tooling, or jig fixtures are required, which results in a lower customer cost per enclosure. No special hand tools are required for equipment or rack installation.


The A & J Engineering Department utilizes the latest Cad design software and employs an experienced registered professional engineering staff.
