Product Description

KoldLok® 3″ Extended Raised Floor Grommet

Part Number: 46-4000-10012

The KoldLok® 3″ Extended raised floor grommet is designed to seal a variety of existing perimeter openings, with the added flexibility of modification for large and unique openings. Based on measurements at multiple data centres, between 50% – 80% of conditioned air is not reaching the air intake of IT equipment due to unsealed flooring openings. This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies and increasing infrastructure costs. By sealing cable cut-outs with KoldLok® raised floor grommets you can address this bypass airflow, so drastically improving the cooling capacity within the data centre and preventing the detrimental effects bypass airflow has.

Also available in a 60″/1524mm length (46-4000-10097) which is supplied without end caps.
