The roll of tape *can* escape through the 6x6 cable cutout under the rack if there aren't too many cables in the way. If we had overhead cabling and under-floor cooling, we'd have no large cutouts anyplace. :) (Alas, the data center across the hall is 27 years old, and we'll need to build a new one to fix it. Someday soon, maybe. :)
