CompX International Inc. CIX

Company Overview

CompX International Inc. is a U.S.-based manufacturing company that designs, produces, and markets engineered components for security and recreational marine applications. The company operates primarily in the security products and marine components industries, serving original equipment manufacturers, distributors, and institutional customers. Its core revenue drivers are mechanical and electromechanical locking systems and precision control components used in marine vessels.

The company’s primary business lines include CompX Security Products, which manufactures cabinet locks, electronic locking systems, and security solutions, and CompX Marine, which produces throttle controls, steering systems, and rigging components for recreational boats. CompX is positioned as a niche, engineered-products supplier with long-standing customer relationships, proprietary designs, and manufacturing expertise in low-volume, high-reliability components. The company traces its origins to businesses developed within NL Industries and became a separately traded public company in the 1990s, evolving through internal development rather than large-scale acquisitions.
