Sargent & Greenleaf
Sargent & Greenleaf introduced its first combination lock in 1857 under the name Sargent's Magnetic Bank Lock. The lock was so impressive that it was used by the US Treasury Department. That early success was born of hard work, innovation, and craftsmanship. These traditions continue to this day, which is why S&G enjoys a solid reputation of dependable products and unequalled support. From Group 2 safe locks to rugged vault locks, S&G has set the standard others have tried to emulate for nearly 150 years.
