KoldLok 3030 Split Integral Grommet - 10 Pack

Upsite Technologies KoldLok Raised Floor Grommets are 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.

Note: This Raised Floor Grommet is sold in a pack of 10.
