I bought a 6U rack and am very impressed with this unit. The corners are fastened with 4 screws each, offset in height and running either in front of or on the side of the device. This made for an incredibly strong structure that had very little flexibility. I didn't use wall screws, instead replacing a couple of 1/4" x 2-1/2" lag screws directly into the wall studs after pre-drilling the holes. This wall-mounted rack is absolutely motionless. I looked up the actual weight capacity and couldn't find it in the specs, although the comments said it was 50lbs. I know it will hold a lot more weight than this. It feels like I can SIT on it. Like I said-- - RELIABLE and will meet my needs for the rest of my life. I highly recommend!
