One for the Europeans. Does anyone have a source for holding down straps ? I can only find complete holding down sets. I'm talking of the sets in red stands. I'm looking for just the straps with the dog toothed ends that match the triangular raising blocks. The ones I have are only short and result in the bolt fouling the bottom of the raising block when used at full height, Pictures of complete sets seem to show much longer ones, but they never seem to be offered seperately. Ideally to suit 8mm bolts.
