Yes, had a look and found a sticker which I had not seen before.can you take a picture and post it up? any marking on them at all?
the 'VW' ones are made the OMTEC, mine have a sticker on the underneath of the rail
the sticker is OMTEC 1453
KBA 31353
Where is the best place to get them Not MainAgent please.
I would expect them to have a reasonable load rating
