Each block hangs from a forged alloy, heat-treated rigid hook, not a swivel, and is made in the USA. The 6\" and 8\" sheave sizes share a common hook assembly that interchanges across the McKissick 4-1\/2\" to 14\" size range, so crews and dealers running mixed rigging inventory can standardize on one hook style instead of stocking separate hardware per block size.
