following conditions:
The RC9AM2STC Poke-Thru Stem with the RC9CMDTC Service Head Fitting, the RC9AMDTC factory assembled poke-thru
device, and the RC9APTC Abandonment Fitting 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 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 – Minimum of 2' [610mm] OC and not more than one unit per 65 sq. ft. [6 sq. m] 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 3" 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:
The “TC” suffix letters indicate that device may be installed on tile or carpet covered concrete floors. All catalog numbers

(A) Maximum number of 22 AWG conductors in low voltage compartment of poke-thru fitting (4-pair cables have (8)
conductors). When conductors larger than No. 22 AWG are used, the aggregate cross-sectional area of the copper
conductors shall not exceed the aggregate cross-sectional area of the 22 AWG conductors permitted in the low
voltage compartment.
For use on carpet covered and tile floors up to 3/4" [19.1mm] thick.
