jk999 , did you not get a recall on the clamps you have ?
I only ask as clamps older than 5 months are suffering failures , dont think it was all clamps , only certain batches , the cam mech in them can go a bit iffy, if you are concerned it may be worth a call as you might well get the mk2 set FOC .
Some blokes ladder went adrift on the motorway and they dont want it happening again !
I got them today , i wont mind taking the ladders off from now on , i also went for the ulti bars in the end as the rhinos nearly put my back out when i went to pick them off the shelf , hard wearing yes , but i have just halfed my payload so weight is a big issue for the new setup.
Thanks all for input. Rich
