FLOOR PREPARATIONS

Step 1 Layout and locate position of hole(s).

CAUTION: Minimum spacing of 2ft on center and not more than

one device per each 65 square feet of floor area in
each span.

IMPORTANT: Please read all instructions

before beginning.

Step 2 Remove 7 1/4" dia. [166mm] section from

carpet or tile. Use template provided.

removing (5) 8-32 screws.

Step 3 Remove 3/4" plug from small

cover plate by rotating counter­clockwise using a large straight

lade screwdriver. Install 3/4"

conduit fitting (provided) into
opening on large cover. Repeat
procedure for 2" conduit fitting,
on large cover plate. (provided)

Step 4 Feed 3/4" inch flexible conduit

into 3/4" conduit fitting on cover
plate. Feed power wires through
small compartment and into the
junction box. Make wiring con­nections in the junction box.
Refer to copper cross section
chart to determine quantity of
wires to pass through each open­ing. Attach cover to the flange
using (2) 8-32 x 3/8" screws.

Step 5 Feed data wires through larger compartment and through

2" conduit fitting on cover plate. Refer to copper cross
section chart to determine quantity of cables to pass
through each opening. Attach cover to the flange using
(3) 8-32 x 3/8" screws.

NOTE: Splices must be made in junction box.

NOTE: If necessary remove Feed Plates to pull communications wires through

Poke-Thru device. Replace Feed Plates when finished pulling wires.

CAUTION: To maintain fire classification, Feed Plates must be installed.

Evolution Series Poke-Thru Devices are UL Listed and Classified to U.S. and Canadian safety standards to the
following conditions:

The 6STC Poke-Thru Stem with the 6CFFTC Service Head Fitting, and the 6ATCFF factory assembled Poke-Thru device are
for use with 1-, 1 1/2 -, or 2- hour rated unprotected reinforced concrete floors and 1-, 1 1/2 -, or 2- hour rated floors employing
unprotected steel floor units and concrete topping (D900 Series Designs), or concrete floors with suspended ceilings. (Fire resistive

esigns with suspended ceilings should have provisions for accessibility in the ceiling area below the Poke-Thru fittings).

d

The assembled Poke-Thru stem and service fitting will not reduce the ratings of the floor assembly when the thickness and type
of concrete (required for the specific rating) are within the specified limits and the fittings are installed as specified:

1. Spacing – Minimum of 2' [610mm] OC and not more than one unit per 65 sq. ft. [6 m

2

] of floor area in each span.

2. Concrete – Minimum thickness of structural concrete topping of 2 1/4" [57mm] over metal deck or a minimum 3" [76mm]
thick reinforced concrete slab. Unit weight of concrete to be 110 to 155 pcf.

3. Installation – Mounted in a 6" [152mm] diameter hole in concrete per installation instructions accompanying
the fittings. For use with power circuits, data and/or audio/visual cables as tabulated below:
