KoldLok Wave Split Integral Grommet

Designed to seal openings in new raised floor cutouts prior to the installation of communications, power, or other cabling.

In a study done by Upsite Technologies on 19 computer rooms totaling over 204,400 ft2, it was found that 60% of valuable cooled air is not reaching the air intakes of IT equipment. The KoldLok Wave™ was developed to provide the best seal against this wasted bypass airflow.


By sealing cable openings and blocking bypass airow, the KoldLok Wave™:

  • Increases cooling unit effectiveness
  • Allows for greater IT density in data centers
  • Increases static pressure under the raised floor
  • Improves cool air delivery through perforated tiles and floor grates
  • Decreases humidity control expense
  • Meets a prerequisite for hot aisle/cold aisle best practices and containment strategies
  • Reduces the need to purchase additional cooling units


Sealing Effectiveness – New, patent-pending wave shaped thermoplastic elastomer offers the best sealing against
bypass airow, unsurpassed by any brush grommet on the market.

Usable Cable Area – Offers 45.5 sq inches of usable cable area, over two and a half times that of a leading brush

Maintenance Free – Wave shaped material seals around cables with no additional maintenance or monitoring

Configuration – Split design allows edge-cut tiles to be removed without capturing cables.

Fire Resistant – Thermoplastic elastomer material is rated UL94 HB.

Longevity – Durable, impact-resistant ABS frame.

Safety Cover – An optional cover is available to ensure greater safety before rack and cable installation.
