For cabinets with four to six cables only, a cabling spool bar is installed on the rear door of the cabinet. If cabling spools are not already installed on the rear door of the cabinet, then they can be ordered as a kit (2021-K220-v001) with the spools attached to the bar. Install the cabling spool bar as follows:
Align mounting slots in bar with pem nuts on rear cabinet door.
There are five sets of pem nuts on lower half of rear door where bar can be installed.
Thread the two screws into the pem nuts and tighten.
