NATIONAL TELEPHONE SUPPLY CO

National Telephone Supply Co. specializes in the precision manufacturing of specialized metal components for defense and federal applications, with a primary focus on fabricated metal products used in military wire and cable systems. Their core capabilities include the design and production of swaging sleeves, cable repair fittings, and custom fabricated metal hardware, leveraging cold-forming, stamping, and precision die processes to meet stringent military specifications. The company demonstrates deep technical expertise in high-reliability metal fabrication for harsh environments, particularly in applications requiring consistent mechanical integrity under vibration, thermal stress, and corrosion exposure. Their specialization in swaging components and cable termination hardware positions them as a niche supplier for mission-critical electrical and signal systems used in avionics, field communications, and vehicle wiring harnesses. The contractor maintains a consistent relationship with the Department of Defense, supplying components for maintenance, repair, and overhaul programs across multiple branches. Work for DLA Aviation and other DoD entities centers on spare parts and repair kits for legacy and active-duty systems, indicating a focus on sustainment and logistics support rather than new procurement. Their engagement with the General Services Administration suggests supplemental supply chain roles in government-wide procurement channels. Primary NAICS codes reflect a focus on miscellaneous fabricated metal products and specialized tooling, indicating a capacity to produce custom, low-volume, high-precision components not covered by standard hardware categories. This aligns with defense supply chains requiring bespoke solutions for obsolete or classified systems. The company’s geographic base in Cleveland, Ohio, supports access to Midwest industrial supply networks and skilled metalworking labor. As a small business structured as a 2L entity with no formal government certifications, National Telephone Supply Co. competes on technical precision, responsiveness, and proven reliability in producing mission-critical metal components for defense applications.
