Poor machining. This is the side - it’s a metal frame with wood insert, preassembled. 

One wall was fine. The other one had 56 screws pulled out and holes stripped. Screws were screwed in a variety of angles and had pulled out 

The black tabs also don’t fit within the grooved areas - this was a problem that would be noted at assembly and packaging but It was sent anyways. 

DO NOT RECOMMEND.
