Hi,

I bought them in Migros DIY centre at Brunau park. I can try and take some photo's for you.

They are basically black (although might be avail in white as well, can't remember), square, at one end is a foot with a thread for fine adjustment, the other end is removable section and there are holes in the pole where you can put a metal pin through to adjust the height.

I am not using mine at the moment, but hte horder in me want's to hang onto them just in case.....
