We always try to keep all cable runs loose in floors, conduits and raceways
because we know that as a facility ages there will be people pulling in new cables and
pulling old ones out. It keeps our cables from being stretched tight around corners and also
leaves a little extra length on the cable incase it ever needs to be re-tipped or moved.
Also, sometimes the building will shift and settle and put pressures of one type or another
on cable runways.
