Evolution Series Poke-Thru Devices are UL Listed and Classified to U.S. and Canadian safety standards
to the following conditions:
The 4STC Poke-Thru Stem with the 4CTC Service Head Fitting, and the 4ATC, 4ATCP2R, 4ATC2P4R or 4ATCP2CR factory
assembled Poke-Thru devices 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 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 4" (102mm) diameter hole in concrete per installation instructions accompanying the fittings.
