In reply to Hugh Cottam:
> Hi David, this is the first case I've heard of this. Are you sure that the ladderlock buckles are correctly threaded. I can send you a picture of the correct threading if you'd like. Failing that it should be possible to thread them back on themselves to prevent slippage. Can you also tell me the model and the age please?
Hugh, it is a black ice. Must be over ten years old and has had this problem since day 1. Please send me a picture, Thanks.
PS. I'm sure doubling them back would work, but would make the system unadjustable en route.
