The lock has a plastic latch that does break. The entire cabinet is cheaply made. If you need a file cabinet that will last spend the extra money and buy a HON. 
The cabinet arrived very beat up. When I opened the box it had several large dents and was bent so bad that the drawers would hit on the corner to close. It came dented on the bottom of the cabinet so much that it won’t sit flat on the floor. 


Pros: inexpensive
Cons: cheaply made
