having now purchased a pair of scotches for lightening ( my mk 1 explorer) i got back to the shed to discover in the two bags containing the ropes i have a lenth of chain 24 or so inches then the wire rope then another 24 ish inches of chain , 1 chain and the wire rope seem to be the right lenth so my question is what is the purpose of this 2nd chain if any or am i lucky enough to have to bits of spare for whatever ? thanks andy
