The Model 6140 goes beyond traditional locks to bring the benefits of current micro-processing technology to your security application. Designed to provide superior security for single door access, the Model 6140 is a sturdy, surface-mounted door lock that combines the 6120 or 6123 safe locks with a modified version of our U.S. government latching extension. With tremendous flexibility and greater management control, this lock is used in ATM rooms, telephone and computer equipment rooms, day gates for vaults and any controlled area where an auxiliary security door lock is beneficial.
