Description
BC-149 DOUBLE CYLINDER refers to a type of locking mechanism used in doors. The term “BC-149” is likely a product code or reference number for this specific cylinder. A double cylinder lock requires a key to lock or unlock the door from both the exterior and interior sides. This means that a key must be used to operate the lock from both sides of the door, providing an additional layer of security. Double cylinder locks are commonly used in situations where extra security is desired or required, such as in commercial buildings or doors with glass panels. The BC-149 DOUBLE CYLINDER is designed to provide enhanced security and control over access to the door.
