Claim 17:
18. A method of creating a pocket in concrete for post-tension tendons comprising:
providing a one-piece post-tension tendon pocket former comprising:
a pocket section configured to create the pocket in an edge of concrete, said pocket section including a first end, and a second end;
a formwork securing mechanism connected to the second end of the pocket section, said formwork securing mechanism is configured to secure the second end of the pocket section to a formwork;
an anchor securing mechanism connected to the first end of the pocket section, said anchor securing mechanism is configured to secure the first end of the pocket section to a post-tension tendon anchor with at least one fastener hole, the anchor securing mechanism including:
an anchor sealing portion configured to seal the first end of the pocket section to the post-tension tendon anchor;
at least one retention tab extending from a side of the pocket section, each of the at least one retention tabs is configured to be secured in one of the at least one fastener holes of the post-tension tendon anchor for securing the seal between the anchor sealing portion and the post-tension tendon anchor;

forming the pocket in the edge of the concrete with the provided one-piece post-tension tendon pocket former;
wherein forming a pocket in the edge of the concrete with the provided post-tension tendon pocket former includes:
drilling at least one hole in the formwork at a desired position;
attaching the formwork securing mechanism to the hole drilled in the formwork;
attaching the anchor to the anchor securing mechanism including pushing each of the at least one retention tabs into one of the at least one fastener holes;
positioning the formwork in a desired location for the concrete;
attaching a tendon to the anchor;
pouring the concrete;
waiting for the concrete to set; and
removing the formwork from the edge of the concrete, whereby the post-tension pocket former remains attached to the formwork and pulls away from the anchor where each of the retention tabs breaks away from sides of the pocket section, thereby creating the pocket in the edge of the concrete configured to allow tension to be applied to the tendon connected to the anchor, a cable to be cut, grease cap/corrosion protection installed, grout applied, or combinations thereof.
