What The Durham does

The Durham Company, founded in 1959 and headquartered in Lebanon, Missouri, is a privately held industrial manufacturer of electrical utility metering and distribution equipment. The company's product portfolio centers on meter sockets (residential, commercial, and instrument-rated configurations spanning 100-5,000 amperes and up to 35 KV), socket-breaker combinations, test switches, pad mount primary sectionalizing and metering enclosures, secondary connection pedestals, and high-amperage termination cabinets. Supporting sub-brands include ATLAS metering mounts, C-Line electrical connectors (Lebanon, MO facility), GEC Durham Industries (instrument transformers, operated as a wholly-owned subsidiary), and L&W Industries LLC (Strafford, MO manufacturing). The company also offers contract manufacturing and OEM services covering design, fabrication, welding, machining, assembly, and finishing.

Products are manufactured from G-90 galvanized steel with NEMA 3R enclosures, hold UL67, NEC 2020/2023, IEEE C57.12.28, IEEE C57.27, IEEE C12.11, ANSI C12.9, and REA certifications, and are protected by three US patents (covering generator transfer switches and AMX Series pad mount equipment). Manufacturing is distributed across six Missouri facilities: headquarters in Lebanon, two Houston MO plants, the C-Line connector facility in Lebanon, L&W Industries in Strafford, and a new facility under construction in Buffalo (ground broken 2024).

The company sells through direct enterprise field sales, phone, website contact forms, and downloadable catalogs on a quote-based pricing model. Customer segments include electric utilities (primary), residential construction, commercial/industrial, and OEM partners. The company is led by CEO G.T. Carr and operates as a closely-held private corporation with no external equity investment identified.
