[RE-wrenches] Wire management devices

[Christopher Warfel]

Thanks Rob, We have been using Unirac for many years and slow to change 
(since we have so much of it in inventory). I think with the difficulty 
of pv module disconnects now, and good wire management, a barrier is 
really a solution looking for a problem.  I'll take a look.  Thank you 
again.  Chris

This is not a main one in my opinion, and given that there are no good solutions indicates to me that it is mostly an unsolvable problem unless you wish to be impractical.  All I asked for were products that could provide a solution. .  I have inspected in several states with solar programs that will not enforce securing electrical enclosures in living spaces that have access to 240 v. I even seen this situation in a children's play room.
