Help to identify this solar racking

Hi Everyone

I need some help to identify the brand of this solar racking. It was from a 1.5kw system in Australia and Im wanting to install onto a shed roof.

I went go Go Electrical today to see if they could help.. They sell a single brand of racking and its not a match.

I then went to Turks, same deal - different racking and no help identifying it. I need earth clamps - Can someone here please help identify the brand of racking as pictured or advise where I can buy earth clamps to suit?

Functional earthing can be done with a crimp lug on the cable + a stainless bolt + a stainless star washer (+ flat washers if needed).
The star washer is a must - it's to break the anodizing & get a good connection.
If you only drill the rail at the end ie past the mount & panel clamps, you don't affect it structurally.
You could drill the single flat parts, eg top right lip or bottom right lip.
