* Category 6 Augmented cable for 10 gigabit ethernet – max allowed cable diameter per Addendum 11
to ANSI/TIA-568-B.2.
NOTE: Prewired downward facing
covers are punched in line
for a sleek flush look. Power
conductors are provided in
the lower channel. Additional
wires can be field installed
and should not exceed totals
above. Communications are
to be installed in the top

* Entrance end fitting fill rate is calculated using backfeed capability and radius inserts. Inserts are removable and fitting can obtain maximum
raceway fill from utilizing end fitting knockouts and removing radius control inserts.
** Calculated using radius control inserts. Inserts are factory installed and may be removed if not required to obtain full raceway capacity.
