Abstract
Multi-piece elevator links, which may be of variable length or capacity or both, are produced by cutting a unitary link into two parts and connecting different combinations of shanks and link ends to form the desired elevator link. Rotation of the link ends with respect to the shank may be prevented. Adapters may be employed between the shank and the link ends to provide varying connections.
