Seal Cable Openings and Protect Your Air Pressure.
Unsealed cable cutouts in your raised floor are a primary source of costly cooling loss. The 4" Round Brush Grommet is engineered to seal these openings perfectly, preventing conditioned air from escaping the subfloor plenum while providing a safe, clean passage for your power and data cables.
Featuring a smart split-frame design, this grommet can be installed around existing cable bundles without requiring disconnection—minimizing downtime and disruption. The dense nylon bristles form a reliable air barrier, improving static pressure and lowering energy costs.
Key Features:
Split-Frame for Easy Retrofit: Installs easily around pre-existing cables, saving significant labor time.
Superior Air Seal: Dense, heavy-duty nylon bristles reduce bypass airflow by over 98%.
Durable Construction: Frame is made from high-impact ABS plastic with a UL 94 V-0 flame retardant rating.
Protects Cables: Smooth bristles prevent cable jacket abrasion and damage.
Why Buy From Rack Chill Systems? Stop paying to cool your subfloor. Get the professional-grade seal you need to improve efficiency, shipped fast.
