These security devices represent a physical barrier designed to protect the contents of filing systems. They typically consist of a solid metal bar that spans the width of the cabinet, secured in place with a locking mechanism. For instance, a unit might feature a steel bar that slides into brackets mounted on the cabinet’s frame, preventing drawer access when locked.
The value of such mechanisms lies in their ability to deter unauthorized access to sensitive documents and materials. Historically, they have provided a reliable, low-tech solution for maintaining confidentiality in environments where digital security measures alone may not suffice. The employment of these devices can contribute significantly to compliance with data protection regulations and minimize the risk of information breaches.
