Know before you buy
This model is specifically engineered for Great Lakes ES enclosures measuring 91 inches in height and 48 inches in depth. It is not a universal fit, so ensure your rack matches these exact dimensions before purchasing.
An open pass-through allows cold air to escape and hot air to recirculate, which can create hotspots. The brush grommet seals these gaps, forcing air to flow through your equipment rather than around it, which significantly improves thermal efficiency.
Yes, the flexible brush bristles are designed to accommodate cable bundles while maintaining a tight seal. They provide enough tension to block airflow while remaining gentle enough to prevent damage to your cable jackets.
The grommet is designed for a straightforward installation into the existing rear vertical cable pass-throughs of compatible Great Lakes ES enclosures. You typically do not need specialized tools, though it is best to ensure your rack is powered down or that you have sufficient clearance before starting.
The high-quality bristles are built for the long-term demands of a professional server environment. While they are durable, they are intended to remain in place to maintain a consistent seal, so they should not be frequently removed or handled.
