1. A cap and tube or seal setting apparatus, comprising:
an anchor holding fixture having a surface for receiving a post tension anchor, the anchor holding fixture comprising a block having an opening therein sized to enable entry therein of part of the post tension anchor while contacting another part of the anchor on the surface to limit motion of the anchor, the anchor holding fixture movably mounted to a tube or seal holding fixture fixedly mounted to a support base;
an actuator mounted to the support base and disposed on one side of the anchor holding fixture, the actuator having a movable part thereof disposed toward the anchor holding fixture, a fixed part of the actuator mounted fixedly to the support base;
wherein the tube or seal holding fixture comprises a block mounted to the support base and disposed on an opposed side of the anchor holding fixture to the actuator, the block having an opening sized to enable passage therethrough of a tube or seal while retaining the tube or seal longitudinally;
wherein when the movable part of the actuator is retracted toward the fixed part, a space exists between the movable part and the anchor holding fixture enabling inserting the post tension anchor therein;
wherein the anchor holding fixture is moveably mounted to the tube or seal holding fixture by at least one pin fixedly coupled to the anchor holding fixture and extending through at least one corresponding opening in the tube or seal holding fixture; and
a spring disposed about the at least one pin, the spring arranged to provide force to urge the anchor holding fixture away from the tube or seal holding fixture.
