INSTALLATION INSTRUCTIONS
Installation Instruction No.: 1 003 615 – October 2003
Walker® electrical systems conform to and should be properly
grounded in compliance with requirements of the current National
Electrical Code or codes administered by local authorities.
All electrical products may present a possible shock or fire
hazard if improperly installed or used. Walker electrical products
may bear the mark as UL Listed and/or Classified and should
be installed in conformance with current local and/or the
National Electrical Code.
IMPORTANT: Please read all instructions
before beginning.
Products Covered: 881RC4ATC, 881RC4ARTTC
Step 1 Determine Floor Covering Thickness.
For Floor Covering less than 3/8" [10mm]
thick (carpet or tile): Cut top of box off flush
with concrete surface.
For Floor Covering greater than 3/8"
[10mm] thick but less than 3/4" [19mm]
(carpet or tile): Allow equivalent portion of
box (floor covering thickness minus 3/8" [10mm]
to extend above concrete surface.
For use with no Floor Covering or floor
covering greater than 3/4" [19mm] thick
(carpet or tile): Consult factory.
Step 3 Install floor covering.
Cut circular opening concentric with exposed
floor box opening. Use template on back page.
Cat. No. 881RC4ATC, 881RC4ARTTC requires a
7" [178 mm] opening.
Step 2 Remove top.

881RC4ATC, 881RC4ARTTC.

Step 4 Determine box height to calculate barrier score line.
Determine the letter of the highest uncut section
remaining in the box sidewall after the upper section
is cut away. If any portion of the box extends above
the highest graduation mark, make calculations
based on the letter that appears below it.
Step 5 Cut divider at required score line.
See cross-reference chart at right.
Step 6 Separate barrier.
Step 7 Insert upper portion of barrier
in floor box adjacent to outer
(communication) conduit.
CAUTION: A portion of a letter may be visible in a partial
section. Ignore letters in incomplete sections.
Note the example shown.
Saw Cut
“G” Section
EXAMPLE: The box is actually
cut in “G” section;
however, “F” is the
highest uncut section. Cut barrier to
length based on “F”
section directions.
EXAMPLE: “F” cut in box
requires divider
to be cut on “A”
score line.

Actual distance between top of box (after
removing excess top) and top of divider
is 2-3/8" [60 mm]. If uncertain where
to cut divider for regions between letters
(through horizontal bar), Cut divider to
measure a minimum of 2-3/8" below floor
level. Can be slightly less if thick floor
covering is used.

Step 8 Power Activation
Cat. No. 881RC4 This activation is
pre-wired. Connect receptacle leads
to circuit conductors with wire nuts
or other approved methods.
Wire according to required
configuration. See schematic below.
If circuit is connected to an isolated
ground, apply IG icon on receptacle
slide as shown.
Step 9 Insert cover assembly into floor box
opening. No glue required.
Orient alignment keys to adapter
with channels in floor box and push
downward. Cover assembly is
secured in place with ratchet fingers.
Step 10 Pull communication cable through
opening in bottom of activation then
through cover as shown.

Circuit “B”
NOTE: The orange triangle shall only be placed on devices that
are wired for isolated ground. See NEC 250-146(d).
CAUTION: Receptacle mounting means not grounded. Grounding
wire connection required. For isolated ground wiring,
connect ground leads to a separate isolated grounding
conductor. See NEC 250-146(d).
CAUTION: Opening on side of adapter must be positioned directly
over the divided side of the floor box. This will allow the
divider and adapter to overlap, maintaining passage of
communication wiring and separation of services.

(TracJack Modules not included, sold separately.)
Step 12 COMMUNICATION CIRCUIT CONNECTIONS
Wire communication devices per instructions provided with product. Mount in poke thru per illustrations shown below.
Communication inserts may be mounted either flush or recessed. Some inserts, such as fiber optic, must be mounted
recessed in order for slides to close properly.
NOTE: GASKET AND GASKET SUPPORT
MUST BE REMOVED BEFORE
WIRING DATA CONNECTIONS
NOTE: To maintain UL Fire Classification, all communication modules or blank inserts (factory or customer supplied) must be UL Listed Communication
Circuit Accessories, and must fit securely in the supplied communication bracket or housing with no visible openings between the modules and
bracket/ housing. Supplied foam plugs must be used when passing cables through the communication openings.
CAUTION: De-energize circuit if activated.

* Caution: Installation must comply with NEC & local code
conductor volume requirements. Available volume for a
dual service installation at 4 inches (102 mm) is 13.4 cu.
in. (220 ml). Minimum height of box should be based on
necessary wire fill requirements.
1. To calculate box fill capacity, use the displacement of the largest uncut section remaining.
2. The distance between the box cover to the top of the divider is 2-3/8" [60mm]. If uncertain which
score line to use to cut the divider, measure a minimum of 2-3/8" below floor level to the top of the
divider. This measurement can be slightly less if a thick floor covering is used.
