Solid Channel Type Cable/Instrumentation Trays (HELP QUICK!)

[nkb79]

I need to find a solid, channel type cable tray fiberglass/stainless steel that does not require angle clips or any type of seperate fastener (i.e. the flanges flare out so that the tray can be fastened itself to the support structure... The trays will be installed upside down over stainless steel conduit to protect the conduit from being contaiminated by welding byproducts to prevent future corrosion of the conduit from saltwater. The tray will have to be able to be removed quickly...

ANY HELP WILL BE GREATLY APPRECIATED.
