Abstract: A termination anchor having a neck region, a mid region, and a distal region. An expanding passage through the anchor from the neck region to the distal region is bounded by an internal surface. Exposed strands on a cable are trapped within this expanding passage by infusing them with liquid potting compound (either before or after the strands are placed within the passage).

By transferring some of this stress, a more uniform stress distribution and a lower peak stress are achieved.
