Thought I would share this with you all. At Axpona last month I paid attention to who used cable risers and if any seemed truly committed to them.
The answer is- maybe 70% of the rooms use risers at all.
Of that 70%, none seemed to care that the cable did touch the floor
in places or another cable. I start to think these folks use them because they feel they "should".
There was one room that had all the cables properly segregated and above grade.
Darned if I can recall who though!
