Vehicle Advertisement Extrusion

[Westcoast Sign Guy]

Anyone know some vendors or mfg's who make those extrusions for holding a aluminum advertisement or name plaques used on the sides of big rig trailers/ buses or smaller truck trailers? They look like a sign cabinet retainer but it just holds a flat piece of aluminum or other substrate in place on the sides?

Thanks in advance

If it's small, could be a name tag holder, maybe Jds industries or jps?

We've used J-channel for mirrors.
