I had to remove the wall mounting plates to align them according to the installation drawings. This required the use of a pair of wrenches. The problem is that nuts and bolts are not metric and not standardized. Sloppy fit for 14mm and too big for 9/16 inch. To get into the rack, a wall mounting plate had to be moved 640mm 3/4" from the recommended position. It didn't seem to pose any problems. Installation was a problem as I had to find the right hardware to secure the drywall install.The second wall mount was in a cinder block wall and I used Tapcons for it.Compared to other mounts bought in the past the metal seems a little flimsy.I will keep an eye on it to make sure I don't glitch in the future I would recommend finding a mount with wider wall mount plates that make it easier to hit the stud.
