rails... a couple of questions

[bxl_lad]

Hi,
I have rails on both sides of the van. On the slider side there's the awning mounted...
Firstly how to identify which brand of rail i have? There seems to be no obvious markings... I figure the two likely options are Reimo or Brandrup?

Anyway, reason i ask, I was thinking of mounting some sort of clothes drying attachment to the rail on the other side of the van (something like the image below), or from this link:

This one seems T5/6 specific though...

Anyone found something similar for a T4 rail (and why i need to know which i have in case they're specific), before i break the tools out and knock something up - maybe the more fun option anyway (it doesn't look like it will be rocket science to build)!

Cheers!
