    Model 2740 Electromechanical Combination Lock

    Meets Federal Specification FF-L-2740

    Advanced electromechanical security.

    The S&G® 2740 lock is engineered and manufactured to meet the highest security standards of the US Government for the protection of classified materials.

    Easy to install.

    The S&G® 2740 uses S&G’s “Magic Module®” footprint to conform to
    the default industry standard for case size and mounting screw locations. This translates into easy installation on new containers and headache- free retrofits on existing units by eliminating the need for mounting plate or boltwork modifications. In addition, the 2740B has a bolt throw of .461 inch to accommodate the boltwork of some older GSA containers, and the lock bolt is even drilled and tapped to match most bolt extensions currently in use.

    Spy-Proof ® Dial.

    This security enhancing feature is standard with the S&G 2740 lock. It restricts the area of the dial that can be viewed to a small band of numbers at the very top, making it extremely difficult for anyone other than the operator to view the numbers being dialed.

    One-Handed Operation.

    Even with its enhanced security features, the Model 2740 is easy to operate. It uses the familiar left-right-left dialing procedure, and allows direct dialing to numbers. There’s no need to count turns of the dial. This makes the 2740 the fastest lock to dial, hands-down.

    Rugged Construction.

    The Federal Specification requires the lock bolt to withstand 600 pounds of force. The S&G 2740 lock easily meets this figure to provide extra protection against brute force attacks.
