INDUSTRY STANDARDS
Designed to meet the following standards:
•
Flame resistant VO rating per ANSI/UL94 (“Tests for
Flammability of Plastic Material for Parts in Devices and
Appliances”)
•
RoHS compliant
•
2008 NEC code compliant with requirements of Article 645.5 (D)

APPLICATION
These Floor Brush Kits provide convenient, safe passage of cables
from under a raised floor application into a cabinet or rack. The
overlapping brushes conform around the cables and block the flow
of cold air. This improves equipment and energy efficiency, reducing
operating costs by minimizing or eliminating up to 90 percent of
cold air leakage through the raised floor cutout.
FEATURES
•
Blocks up to 90 percent of cold air leakage around power and
data cables
•
Flush mounts provide a low profile and grommet to raised-floor
panel cutouts (required by NEC and NFPA)
•
Surface mount provides an easy-to-use retrofit to existing
raised-floor cutouts
• Adjustable flush mount provides an extra-large cable capacity
and can be cut to size to fit the application
• Overlapping bristles conform around data and power cables to
minimize air leakage through raised floor and improve overall
cooling efficiency
• Reduction of cold air loss through raised-floor plenums helps to
increase under floor static pressure
• Cover provides protection during build out
• Smooth, rounded low-profile flush mount edges protect cables
from sharp raised-floor edges
• Two-piece surface mount and adjustable floor brush kits have
self-sticking adhesive to expedite installation
• Raised-floor tiles need not be removed for installation
• Brush kits can also be used on cabinets or other locations
that need to provide cable egress and prevent air leakage or
contaminants from entering
• Self-tapping screws included
SPECIFICATIONS
• ABS polycarbonate housing
• Nylon polymer bristles
• EPDM gasket
