ABSTRACT:
An anchor for a post-tension anchorage system includes an anchor member with an end surface, a polymeric encapsulation covering the anchor member having a tubular section extending outwardly from the end surface of the anchor member, and an improved cap having a generally tubular body with an open end and a closed end. The tubular section of the encapsulation includes an inwardly extending protrusion. The improved cap has a flanged end adjacent an open end of the tubular body of the cap. This flanged end has a circumferential surface. A locking member is formed on the circumferential surface for detachably engaging the protrusion such that the flanged end is fixedly received within the tubular section. A compressible seal is affixed within the polymeric encapsulation and extends around the end surface. The cap has an annular surface extending around the open end and in compressible contact with the compressible seal when the locking member engages the protrusion.
