6" Evolution Series Poke-Thru Devices
WIREMOLD
®
Evolution Series – The Most Innovative Poke-Thru
Devices in the Market
Designed for retrofit and new construction, Evolution Series 6”
Poke-Thru devices provide convenient access to power,
communications, and audio/video services recessed below floor
level - providing maximum device protection. With 3-gangs of
capacity that allow you to configure services for the needs of your
space, services can be placed in any location within the unit.
The low-profile durable metal covers are available in six powder-
coated finishes, designed to match any space. The cover also
features sliding doors that allow cables to neatly egress from the
unit, protecting cables while reducing tripping hazards.
Evolution Series 6” Poke-Thru devices are the perfect fit for
meeting and training rooms, classrooms, healthcare facilities or
commercial buildings with open-space architecture.

FEATURES & BENEFITS
n
Recessed devices.
Three (3) compartments for power,
communications, and/or A/V devices, all recessed 4"
(102mm) below the floor level, providing maximum
protection and device longevity.
n
Die-cast aluminum cover assemblies.
The Evolution
Series poke-thru design includes all metal die-cast
aluminum cover assemblies, available in powder coated
finishes of black, brass, gray, nickel, bronze, and aluminum.
n
A/V compatible design.
The 6AT Series devices are
designed to work with with Legrand's AVIP devices. Also
compatible with most A/V manufacturers devices including
their 1-gang decorator style design.
n
Flush tile version cover assemblies.
A flush style cover
for tile applications allows the Evolution Series Poke-Thru
Devices to be adjusted to the same level as the top surface
of the floor covering. The tile cover is designed to be used in
higher traffic applications, where a low profile is a must.
n
Auto-close egress doors.
Egress doors lock in position
when slid open and automatically close around cables,
reducing the egress opening to the smallest size possible.
n
Improved hinge design.
Provides greater durability while
creating a more fluid, intuitive, opening and closing motion.
n
“Step-on-it” installation.
Quick and easy installation without
the need for additional fasteners or a second installer.
n
Added furniture feed capacity.
The 6ATCFF Series
Poke-Thru Device offers the largest dual service furniture
feed capability on the market.
n
Pre-pour sleeve.
Creates a removable cast-in-place
core hole that allows the contractor to position poke-thru
units before concrete is poured. Eliminates the cost and
labor of coring the opening.
n
TopGuard
™
Protection.
All Evolution Series Poke-Thru
Devices, like every Wiremold Poke-Thru Device, meet and
exceed UL scrub water exclusion requirements for tile,
carpet, and wood covered floors.
n
Meets ADA Accessibility Guidelines.
Wide trim flange
is designed to meet the ADA Accessibility Guidelines as it
pertains to ADA Standard 4.5 which addresses changes in
floor and ground surface levels. The poke-thru trim flanges
are beveled so the slope is no greater than 1:2 ratio.
n
Suitable for use in air handling spaces.
In accordance
with Sec 300-22(C) of the National Electrical Code.
n
UL Listed and UL Fire Classified to U.S. and Canadian
safety standards.
UL Fire rated for up to 2-hour rated
floors maintains the fire classification of the floor.

Evolution Series 6" Poke-Thru Device Cabling Specifications
Copper Cross Section:
The copper cross-sectional area determines the amount of wire
fill capacity in a poke-thru device. Unlike other wire and cable
management systems that utilize wire fill capacity, a poke-
thru device is UL tested under fire conditions to determine the
maximum amount of copper conductors that will pass through
a poke-thru device, while maintaining the fire-rating of the floor
assembly. All Legrand Poke-Thru Devices are UL Classified to
U.S. and Canadian safety standards.

These devices meet all UL scrub water requirements,
but are not suitable for wet or damp locations, or
other areas subject to saturation with water or other
liquids, such as commercial kitchens.

UL Certification:
The poke-thru device is fire rated for concrete floor coverings. For floor coverings greater than
1" (25mm), consult factory.
To view the UL certification, please visit www.UL.com/Database. Enter “Wiremold” as the company
name and “CEYY” as the UL Category Code.
Poke-thru devices and abandonment fittings are for use with 1-, 1 1/2-, or 2-hour rated unprotecteed reinforced concrete floor
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 designs with suspended ceilings should have provisions for accessibility in
the ceiling area below the poke-thru fittings).
The assembled Poke-Thru stem and service fitting or the abandonment fittings 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
–
2. Concrete
–
Minimum of 2' (610mm) OC and not more than one unit per 65 square feet (6 square meters) of floor area in each span.
Minimum thickness of structural concrete topping of 2 1/4" (57mm) over metal deck or a minimum 3" thick reinforced
concrete slab. Unit weight of concrete to be 110 to 155 pcf.
3. Installation
– Mounted in a 10" (254mm) diameter core drilled hole in concrete per installation instructions accompanying the fittings
or abandonment fittings. For use with power circuits, data and/or telephone cables as tabulated below.
NOTE:
The material that is used in Wiremold
®
poke-thru devices is not listed under the directory for Fire Stopping Material
because the poke-thru device is UL Classified as “Outlet Boxes and Fittings Classified For Fire Resistance (CEYY)”. The
pass/fail criteria comes from UL263. The pass criteria is that the poke-thru unit cannot exceed 325° F. above ambient
before the concrete slab (or deck) reaches this same temperature. Some poke-thru devices are tested for 2 hours while
others are tested for 4 hours. The intumescent material has never been tested as a fire-stopping material as a stand-
alone device. This material is designed to work as a unit with the entire poke-thru device.
