What is this extrusion called?

Not sure what this 90 degree extrusion is called, and I'm hoping someone here can tell me. You can see him tightening a machine screw into it at 05:27 in the video. It's basically just aluminum angle with each side recessed a bit so that whatever you screw to it, sits flush with the bracket.

It might be purpose-made for that particular product. You can have pretty much any shape you want extruded- for a price. Or it might be something specific to that industry. A lifetime ago I used to machine all sorts of extrusions for sailboats. We must have had 100 profiles or more available to us.

It seems like that one would be pretty common though. Lots of people will want a panel to sit flush.

And that depends on the thickness of the panel.
