Can the clear plastic cover covering the HV jacks be ordered so that one doesn have to pull all the plugs in order to get the plastic off?
No, the wiring of the CO cable to the shelf cable via the isolation jacks should be done once. Then, all future changes should be done at a cross connect box or at the 300 V point splice. This is a safety item and a maintenance item. This is part of the design of the isolation. If constant rewiring on the jacks is being done, the cable pairs will become brittle and break. In addition, it is far safer to wire the jacks than make the 300 V point connection. That way one can work the isolation jack connection barehanded, assuming the dedicated cable is open and the pairs are cleared at the 300 V point splice.
