Section D - Cabinet Locks & Latches A NATIONAL LOCK OVERVIEW B A Lock Is A Lock….Or Is It? C Disc Tumbler, Pin Tumbler & Deadbolt Locks: D Disc Tumbler Cam Locks sometimes referred to as “wafer locks” are inexpensive, low security locks with limited keying capabilities. Master keying for E disc tumbler locks is limited to only one level. The disc tumbler lock consists of chambers with only one disc per chamber which raises or lowers as the key passes through the window that is cut into the disc. Disc tumblers are not intended for high-use or high security applications because they wear out quicker F and are easier to bypass than pin tumbler locks. G Pin Tumbler Cam Locks are medium security utility locks that have greater keying capabilities. In commercial applications where large numbers of locks will be installed within a facility, pin tumbler locks are typically used because they allow the more complex master keying required in larger H institutional settings such as schools, banks, and hospitals. The pin tumbler consists of chambers that contain at least two pins per chamber which raises or I lowers as the key passes through. This type of lock is harder to bypass than disc tumbler locks. J Deadbolt Locks are typically longer lasting than disc tumbler locks. A cam lock is chosen many times because it is the least expensive and most versatile alternative available. Cam locks, however, do not stand up to heavy use or provide the same level of security as a lock dedicated specifically for K a door or drawer application. Dedicated door and drawer locks have a heavy duty deadbolt to secure the cabinet—a cam lock’s security is only as good as the screw which holds the cam in place. L Understanding Keyed Locks: M 1.
