         tour 140, so that the cable distribution assembly 100 adapts
         to different bore 410 sizes and to different cable 440 thick-
         nesses.  The  invention  contemplates alternative embodi-
         ments in which the shaft and roller are adjustable only hori-
         zontally or only vertically. In the present embodiment, as
         shown in figure 11, the shaft 150 passes through respective
         slots 200 on each sidewall 130. The position of the shaft 150
         along the slots 200 is adjustable. Having a shaft 150 adjust-
         ably connected along opposite slots provides a mechanically-
         and cost-effective solution for providing adjustability of the
         shaft 150 and roller 160 in relation to the base 120.

           The  introductory description  is  presented in  the parent
         application in its description of figures 14-16 of that applica-
         tion. In this application figure 14 also shows a specific de-
         scription of the invention. It is a tensioning device comprised
         of: a gear box 21, a barrel 22 which is tubular shaped having
         an external diameter and a rotational axis along a length of
         the tube, a barrel gear 30 affixed to the exterior of said bar-
         rel with the barrel gear encircling the barrel perpendicular
         to the axis of the barrel’s length, and guide 33 inside of said
         gear box with a stub extending out of the guide. The gear
         box has two holes of which the first hole is situated opposite
         from the second hole, and these two holes are sized to allow   Figure 16:  Assembly  of an embodiment  adapted  for operating in
         the barrel to pass through the gear box and are sized such   compression as a lifting jack.
