KoldLok 3030 Split Integral Raised Floor Grommets

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

Based on measurements at multiple data centers, 50-80% 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.


  • 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


The Split Integral Grommets allow tiles to be moved without capturing cables.
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.

Sealing Effectiveness

100% bypass-airflow sealing in areas undisturbed by cable penetrations at static pressures up to 0.10 inches of water column 100% bypass-airflow sealing with four ½ inch cables penetrating the Grommet at the static pressure required to cool up to 3 kW/cabinet 96% bypass-airflow sealing with four ½ inch cables penetrating the Grommet at a static pressure of 0.10 inches.

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).

Dimensions and Tile Cutting Requirements Inches (W x D x H)

Overall size  – 11 x 8 1⁄4 x 1 5⁄8
Product height above the raised floor – 1⁄8
Usable cable area – 8 x 4
Cut required to install Grommet in interior of the tile – 9 1⁄4 x 6 3⁄4
Cut required to install long side of the Grommet on the tile edge – 9 1⁄4 x 7 1⁄2
Cut required to install short side of the Grommet on the tile edge – 10 1⁄4 x 6 3⁄4

The Grommets satisfy NFPA 75 Section 5-4.4 requirement by self-dressing the raw metal edges of raised-floor tile cable cutouts.
