CoolBalance®- Brush grommets for cable management and air flow control in data centers


The CoolBalance line of brush products provides flexible solutions for sealing cable access holes in data centers. Combining our experience in applying strip brush to a range of sealing applications and our XtraSeal™ technology, CoolBalance brush seals can substantially reduce data center energy consumption. XtraSeal brings the sealing power of an impervious, yet flexible membrane sandwiched between thousands of filaments that effectively seal the openings required for data cable access.

Data centers and computer rooms require large amounts of cooled air to maintain proper temperatures for proper server functioning. Current hot aisle/cold aisle layouts create the potential to have hole cutouts in the hot aisle leaking huge amounts of cooled air into the hot aisle, completely bypassing the servers and communication equipment. This is a drastic inefficiency and waste of energy dollars. CoolBalance cable access hole seals provide cost-effective sealing with rapid payback. Many sealing products on the market are limited in size and shape, limiting installation flexibility. Coolbalance’s range of cable grommet sizes and shapes ensure effective cable management and sealing for balanced air flow, minimal air leakage and, servers and equipment are cooled effectively and cost-efficiently.


  • The CB11 model provides is a rectilinear seal that fits down into the floor and provides edge protection from the rough cutouts. These are available in variety of sizes to fit your needs.
  • Circular brush grommets completely encircle the cables providing an inherently superior seal through its geometry.
  • For existing data centers that may face a wide array of cutout dimensions or challenging installation roadblocks due to existing cabinetry and racks, the CB22 surface mount solution offers a ½” high profile, the CB22 will fit beneath most racks and cabinets. One end of the seal can be removed, the seal placed around existing cables, then the end reattached to complete the installation.
  • Models CB11H or CB22H accommodate openings near walls or other obstructions.
  • For through-wall applications, below the raised floor, the CB44 and CB55 prevent the cooled air from escaping out into the wall interior or into mechanical rooms.
