APC AR7740 KoldLok Extended Raised Floor Grommet | Rack Accessory Kit

Protect cooling efficiency where it is often lost first: at the floor cutout. The APC KoldLok extended raised floor grommet kit is designed to seal cable openings in raised-floor environments, helping reduce uncontrolled air leakage that can undermine cooling performance and increase operating cost. For infrastructure teams managing high-density rooms, the value is practical. Better containment at the floor level supports more stable airflow patterns, which helps cooling systems do the work they were designed to do instead of compensating for open penetrations. The kit format also makes deployment straightforward across multiple openings, whether you are standardizing a new build or tightening up an existing white space. With 10 grommets, an installation guide, mounting kit with pressure-sensitive foam, and self-tapping screws, this APC accessory is built for repeatable installation. TAA compliance adds procurement flexibility for organizations with sourcing requirements, while the KoldLok design gives facilities teams a focused tool for improving airflow discipline in raised-floor deployments.
