Eaton SR1UPANEL50 – 1U Blanking Panel Kit for Rack Airflow

Overview

The Eaton SR1UPANEL50 is a 1U blanking panel kit consisting of 50 individual filler panels used to close unused vertical rack spaces in 19‑inch equipment enclosures. IT infrastructure engineers, data centre facilities technicians, and rack installers use these panels to optimise airflow within server and network cabinets, reducing hot air recirculation and helping maintain consistent cooling patterns.

Each panel is 1‑rack‑unit high and designed for tool‑less mounting into square‑hole EIA‑compliant racks and enclosures. By occupying unused rack slots, these panels prevent air bypass around installed equipment, improving the efficiency of conditioned airflow delivered by CRAC/CRAH systems, fans, and perforated tiles.

The kit’s 50 pieces allow field teams to blank off gaps from 1U up to 50U of vertical space — fitting equipment cabinets of varying heights without the need for individual panel purchases. The tool‑less engagement simplifies installation during rack build‑outs and retrofits.

This solution integrates seamlessly into existing rack infrastructure and is compatible with the SmartRack series and most third‑party EIA‑310 standard racks. It does not provide structural support or cable management features; its purpose is strictly to manage airflow and visual tidiness within enclosed rack spaces.

In practical deployments, these blanking panels are used wherever there are unpopulated rack units — such as below low‑density network switches or above mounted servers — to close open spaces. They are not load‑bearing and should not be relied upon to support equipment weight or act as cable pathways.
