To the ladder rack question, I've only used Chatsworth via Anixter. Good product with alot of additional features, vertical transitions, radius pieces - I think they custom manufactured some tall standoffs for us recently - but I'll need to check on that.

ProfessorShadow: Do you run into issues with the splices of the techflex rolls? I've recently been doing some longer fully socked runs, and have had multiple issues with splices in the middle of a techflex roll.

btw - I like the black. Do you comb out the cable past the sock or leave it be?
