What tolerance off of plumb should a single base station radio rack be installed?

Placing the rack so it sits truly vertical and level is important for mechanical integrity, proper airflow, and reliable connections. Use a spirit level and adjust until the indicator bubble is within the marked area—i.e., just inside the bubble. That level tolerance means the rack is sufficiently plumb without being overly strict. If you push the rack to one end of the bubble or outside it, you’re indicating a tilt beyond what’s acceptable, which can place stress on mounting hardware and misalign cables or airflow. So the best approach is to install it with the bubble just inside the bubble on a level.
