I'm not sure what is going on with quality control for this product, but I ordered two of these and each box was missing something. The first box was missing the back panel, and the second box only had 4 cam locks instead of the required 8. I submitted a customer service request with the company to have replacements sent. Fortunately I was able to use some of the cam locks from the other box to at least get one of these built. Pretty disappointing that two separate boxes both had at least one missing part.
