RELAY RACK PROCEDURE
(6.625” CAVITIES)
Because of their width, 6.625” cavities
are mounted on relay racks in a hori-
zontal or ientation on cavity deck
plates.
1) Determine the location of the expansion chan-
nel in the rack by consulting the new
THRULINE cable chart.
2) If necessary install an empty cavity deck in the
rack using 4 Phillips screws. If there is room on
an already existing cavity deck then skip this
step of the procedure.
3) Mount the cavity on the deck by laying the cav-
ity onto the “V shaped” cavity bracket.
