Cylinder Lock with Dust Shutter

As a deterrent to vandalism, option CLD provides a keyed latch for the door. As the key is pushed into the lock the dust shutter opens. Turn the key. The latch will rotate allowing the door to be opened. As the key is removed, dust shutter closes to prevent dust and other small particles from entering the internal mechanism of the lock ( compare to our -CL option). Typically, a single lock is provided for each door.  All cylinder locks supplied are keyed alike.
