In a study conducted by the Uptime Institute on 19 computer rooms totaling over 204,400sq.ft., it was found that 60% of valuable cooled air was being released by unsealed cable openings. The KoldLok Wave Split Integral Grommet was developed to provide the best seal against this wasted bypass airflow. It was designed to seal openings in new raised floor cutouts prior to the installation of communications, power, or other cabling. The KoldLok Wave's innovative design uses Thermoplastic Elastomer (TPE) which is overmolded to the frame to create a flexible sealing membrane.
