ABSTRACT:
An anchor for engagement with a post-tension tendon includes an anchor base having a generally tapered wedge receiving bore. A sheath surrounds the anchor base. The sheath has a substantially cylindrical extension on one side of the anchor base for contacting the tendon at a distal end thereof from the anchor base. The extension is formed integrally with the sheath and has a seal disposed therein proximate the distal end. A cap having external threads thereon is for engaging corresponding internal mating threads on the sheath on a side of the anchor base opposite to the sheath extension. The cap has a tool engagement surface thereon to facilitate rotation by a tool for engagement with the sheath.
