Abstract

A hook for gripping chain is asymmetrical so that the effective chain length can be adjusted to a part link tightness. The attachment end of the hook is offset from the plane of the hook end, which includes the slot for receiving a link of a chain. If the chain enters from one side of the hook, the chain and hook nave a different angle than when the chain enters from the other side of the hook. The resulting change in angle and hence the way the hook interferes with the chain changes the length of chain required for the chain to reach the slot.
