cable tray profiles

Hi

I am currently working on a large assembly and need to start laying out some cable tray. The problem i am having is that the generic cable tray profile in 'Routing' is different to the cable tray i want to use, my cable tray has slots etc, and i cannot seem to find any cable tray profiles on the internet that i can use as a weldment.

Am i missing something?

Regards.

Leon.
