Schuco Parametric System Plug-in

I'm trying to write a definition supplied by Schuco for their facade system but can not identify one of the components used.  It's not supplied in the plug-in and I haven't found any answers online.  Attached is a picture of the definition, and a close up of the component.  Any help identifying it or an alternative would be greatly appreciated.  

Since I'm posting this, if you have any others tips or pieces of advice on Schuco's plug-in I'm all ears.  I'm an undergraduate architecture student and still learning grasshopper.

Thanks again.
