Abstract
An anchorage for a post-tension system including an anchor body having an interior cavity and a generally flat end surface, a tendon extending through the interior cavity of the anchor body, a plurality of wedges in interference-fit relationship between a wall of the interior cavity and a surface of the tendon, a cap member positioned outwardly of the flat end surface, and a ring juxtaposed against the inner surface of the cap member. The ring is physically deformed so as to provide a visual indication of a desired amount of tension applied to the tendon. The ring is received within an annular slot formed in the flat end surface of the anchor body.
