I think you will find it difficult to adhere to Article 392 and use a cable tray on a rooftop with source circuit conductors, if that is your hope.

We previously used Cablofil and Cablo-port FSL 12" tray but it is very expensive for our current application due to the size of the roof. We need to install about 200' of tray and Cablofil galvanized is eating up the budget. Can anyone recommend a cheaper alternative. -- Chris Mason
