AirGuard’s AirBlock Rubber Gasket Grommets combine UL 94 V-0 rated flame-retardant ABS polycarbonate construction with an EPDM rubber gasket to create a secure seal around cables, reducing air leakage and improving airflow management. Available in multiple sizes and configurations, many models feature pre-cut cable openings, protective gasket covers, and integrated screw toggles for fast, secure installation in raised floor systems.
