Description
A double cylinder lock is keyed on both sides, requiring a key to lock or unlock the door from inside and outside. It offers enhanced security, making it more resistant to unauthorized entry, and is often used on doors near glass to prevent tampering if the glass is broken. Double cylinder locks are ideal for high-risk areas, providing added protection and key consistency.
