Overview

The nVent DFB57F Flush-Mount Floor Brush Kit (SKU: DFB57F) is a heavy-duty, one-piece solution engineered to seal cable openings in raised access floors for data centers, IT facilities, and server rooms. This kit features a two-stage sealing system combining durable nylon brushes with an EPDM gasket to block up to 90% of cold air leakage, improving cooling efficiency and reducing energy costs. The integrated safety cover complies with OSHA jobsite standards by preventing open floor openings during construction, eliminating fall hazards and meeting NEC, UL, and NEMA requirements for cable protection and sharp-edge shielding. With a cable egress area of 7.49 x 4.86 inches (190 x 123 mm), the DFB57F accommodates high-density cable bundles, including Category 5e, 6, and 6A at 60% fill (575, 445, and 309 cables respectively). Made from black ABS, it integrates seamlessly with static dissipative access floor systems while providing a low-profile, flush-mount design. Installation is tool-free for new constructions, and the removable brush allows floor tile removal without cable disconnection. Ideal for minimizing air leakage in raised floor plenums, the DFB57F ensures optimal thermal management and personnel safety in critical infrastructure environments.
  • 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 data center 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
