I recently racked a 9U network rack, with four mounting holes. The right side were all done with 5/16 inch lag screws (top + bottom right). I then used those flip toggles to get the left side since it was abnormal stud spacing. I am running a UPS (30 lb), a 10 lb udm pro, a 10lb switch, 45 lb network rack. I tried putting my weight on it and it' didn't move. I think it's 1/2 inch drywall. Curious if thats enough to hold up the rack without worrying about stuff falling
