Industry-Leading Innovation for 150 Years

Sargent and Greenleaf introduced its first combination lock in 1857—a lock that was so impressive that it was used by the US Treasury Department. The innovation and craftsmanship in that first lock is evident today in our line of mechanical combination locks. With unrivaled dependability and product support, these locks—from three-wheel locks, four-wheel locks, four-wheel vault locks and an array of dials and rings for mechanical combination locks—continue to set the standard, making S&G an industry leader for more than 150 years.
