When ordering an enclosure, we feel that your choices should not be limited. For over 40 years, we have excelled in providing a superior line of precision custom and standard (NEMA, UL, and CUL) enclosures to the electronic, communication, and control industries. Our knowledgeable staff will assist you in selecting, designing, or modifying an enclosure to fit your individual application. Each cabinet is made-to-order directly from your specifications. This flexibility enables us to add detailing at the manufacturing level, eliminating the need for after market reworking.
