Re: Cable calculator

Not so sure about those calculations though...

Vertical Distance: Each U is 1.75 inches (4.45 cm). The distance between
U48 and U22 is 26U (48 - 22). The vertical distance is 26U * 1.75 inches/U
= 45.5 inches (approximately 3.8 feet or 1.15 meters).


Seems like that assumes you're going up & across and down.  If going down
across and up, I'd go with ((48+22)*1.75 = 122.5" == 10.2') 12' or 15'
cables.
