I purchased this patch panel because it had the cable management bar. I wanted the bar because the panel is mounted in as swing-gate rack and I didn't want to risk the connections coming loose. Unfortunately, the bar is attached by dropping into thin plastic loops on the sides to the panel (possible to seeing the pictures, but not easy to see). Any upward pressure on the cables pulls it out. Also, the loops are quite thin and seem unlikely to wear well.
I ended up purchasing a separate cable management bar that bolted in along with the panel.
