A tensioning device is hidden inside the end post with only the head of the Receiver exposed on the outside of the post. The inside is female-threaded to accept the male-threaded Invisiware® Swaging Stud that is attached to the cable. The head of the Receiver is broached for an Allen wrench. To tension the cable, insert the Allen wrench and rotate the Receiver around the male threads on the Swaging Stud. This will draw the Swaging Stud further inside the Receiver as you continue to turn it with the Allen wrench.
Pipe ends are counterbored so the full perimeter of the head of the Receiver will rest on a flat surface in the pipe. The head rests on the outside wall of a flat-sided post. Except where noted, a Plastic Washer is included and acts as a scratch resistant barrier between the Receiver head and the post.
