Airflow Optimisation with Koldlok Floor Grommets

Designed to seal openings in new or existing raised floor cutouts used for communications or power cabling. Based on measurements at multiple data centers, on average 48% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings. This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies, and increasing infrastructure costs. KoldLok® products specifically address bypass airflow and its detrimental effects on data center cooling.


  • Split or Complete frame
  • Interlocking feature that fastens the two halves together
  • The Grommets contain no loose or partially fastened parts, which can become separated or fall through the raised floor
  • The Grommets are impact resistant and durable
  • Dry erase markable surface (non-permanent marker)
  • New and improved finish quality
  • Stronger material – better strength
  • Easier installation
  • Smooth polished surface
  • The Grommets satisfy NFPA 75 Section 5-4.4 requirement by self-dressing the raw metal edges of raised-floor tile cable cutouts
  • KoldLok products are compliant with Directive 2002/95/EC of the European Parliament and the Council on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS)


  • Increased ability to remove and replace tiles with edge cuts
  • Reduced installation labour
  • Ability to custom label grid location or cabinet identification
  • Improved lifespan due to higher impact material
  • Quick removal under low height cabinets due to interlocking design
  • Easier to clean
  • Increases existing cooling unit capacity Reduces the need to purchase additional cooling units
  • Improves equipment reliability and extends equipment life
  • Increases static pressure under the raised floor and improves cool air delivery through perforated tiles and floor grates
  • Facilitates Cold Aisle/Hot Aisle best practices
