MASTER LOCK COMPANY LLC

Master Lock Company LLC specializes in the precision manufacturing of high-security padlocks and hardware components for government and institutional use. Their core capabilities include the production of corrosion-resistant, case-hardened steel and brass padlocks meeting Grade-2 specifications, with engineered features such as keyed-alike and keyed-different systems, dual-key issuance, and precise shackle clearances. The company excels in fabricating solid and laminated bodies from carbon steel, brass, and bronze, ensuring durability under harsh environmental conditions. Technical expertise spans metallurgical finishing, lock mechanism integration, and compliance with federal security standards for physical access control. Their specialization in chain-integrated padlock assemblies and standardized dimensional tolerances demonstrates a deep understanding of procurement specifications used across federal infrastructure programs. The contractor maintains a dominant relationship with the General Services Administration, consistently supplying standardized padlock systems for federal property security, warehouse access, and facility management applications. All recent awards reflect repeat engagements under GSA schedules, indicating a trusted, long-term supplier relationship rooted in reliable delivery of compliant, high-volume hardware solutions. There is minimal evidence of direct DoD engagement, suggesting their primary focus is on civilian federal infrastructure rather than military-specific applications. The primary NAICS codes—332510 (Hardware Manufacturing) and 332999 (Other Fabricated Metal Product Manufacturing)—reflect a focus on standardized metal hardware production, particularly lock bodies, shackles, and integrated security assemblies. The contractor positions itself as a specialized manufacturer of physical security hardware, serving government procurement channels requiring standardized, repeatable, and specification-compliant components. Master Lock Company LLC is a 2L entity headquartered in Oak Creek, Wisconsin, with no active government certifications listed. Its market presence is defined by consistent, high-volume fulfillment of GSA contract requirements, establishing it as a reliable source for standardized security hardware within the federal supply chain.
