The KoldLok® Round, from Upsite Technologies, is now available in two sizes 4″ and 6″.  Both versions of the KoldLok® Round raised floor grommet feature Hybrid Brush Technology (HBT), which combines KoldLok® brush technology with a membrane layer.  The result is a grommet that provides exceptional sealing and airflow management, unsurpassed by other brush products on the market.

The KoldLok® Round is easy to install and as it only requires hole saw installation, the labour time of installation can be reduced by over 50%.

The KoldLok® Round can be used to seal cable openings in new and existing raised floor cut outs. Sealing cable cut outs within the raised floor greatly reduces bypass airflow, increases the useable cooling unit capacity and ensures maximised efficiency from the CRAC unit.

Designed to seal openings in new and existing raised floor cutouts to block bypass airlow and maximise cooling system efficiency.

Both the 4” and 6” KoldLok® Round Grommet feature Hybrid Brush Technology (HBT), making them the premium choice for your facility. Their revolutionary sealing technology greatly reduces costly bypass airflow, increasing usable cooling unit capacity, and ensuring maximised efficiency from HVAC equipment

The KoldLok® Round Grommet allows large cable bundles or PDU plugs to be pulled through the usable area.

  • The Split feature of the KoldLok® Round 4” and 6” allows product installation or removal without disturbing 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.
  • The Grommets feature an extra sealing HBT Membrane Layer.
  • 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 Electric Equipment (RoHS).

  • Improves volume of conditioned air delivery through perforated tiles and floor grates.
  • Compliance with best practices for all raised floor cooling configurations (Hot and Cold Aisle, Hot Aisle Containment, Cold Aisle Containment).
  • Simple, installation saves time and labour and requires no downtime.
  • Round grommets enable hole saw installation which reduces cutting time by over 50%.
  • Durable ABS frame and Hybrid Brush sealing surface can be used for years.
  • Hybrid Brush Technology (HBT)
