Locking Mechanism
The cabinet includes a locking system to secure your documents. Insert the key into the lock on the designated drawer and turn to lock or unlock. The interlock system ensures that only one drawer can be fully opened at a time, enhancing stability and preventing accidental tipping.

Adjustable Hanging File System
