66M to 8 Pin Modular Adapter (USOC)
Fits over the pins on a standard 66M Block (won't fit on a 66B Block). Brings the pins out to a 6-Pin Modular Jack.
NOTE: because of the size, you can't use these Adapters on adjacent lines (pins) on the 66M Block.
8 Pin Modular Jack (RJ-45) wired WECO (568B, not USCO).
NOTE: this Adapter is wired WECO so it works with Ethernet or Merlin equipment. It's not CAT5 rated.
