Built to meet Federal Specification FF-L-2740B for the protection of classified materials, our Model 2740B high-security safe lock is GSA-approved for security containers including safes and vault doors. A standard footprint and bolt throw and a simplified installation process make it easy to retrofit the Sargent and Greenleaf 2740B in existing applications.
Advanced design features and a motor-driven lock mechanism prevent vibration and bouncing attacks. Our Spy-Proof® dial makes it difficult for anyone other than the operator to view the combination being dialed. Familiar left-right-left dialing combined with direct-dial speeds safe opening time.
