(57) A system for use with a post-tensioning concrete anchor may comprise a connector anchor including a bore therethrough, the bore including a first frustoconical portion, the connector anchor adapted to bear on the post-tensioning concrete anchor, and a coupler. The cou­pler may comprise a coupler body including a bore there­through, the bore including a second frustoconical portion that is oriented oppositely to the first frustoconical portion, and a connector having a bore therethrough and configured to receive the coupler body therein, the connector adapted to mechanically engage the connector anchor such that a tensioning force can be transmitted from the coupler body to the connector anchor via the connector. A method of using the system may allow a second con­crete section to be poured adjacent to a first concrete section before the first concrete section has been stressed.
