Measuring 482.6 x 10 x 132 mm and occupying 3U of rack height, it improves the visual appearance of server and network cabinets while helping to reduce dust ingress and direct airflow more predictably.

Advantages

The panel is made of sturdy sheet metal with a RAL 9005 dark black finish that matches typical rack equipment. Its precise 3U dimensions ensure a snug, gap-free fit in standard 19" racks, contributing to a tidier cabinet interior and aiding in basic airflow management.

Suitable for

When it may not be suitable

This blind panel is a passive sheet-metal filler and does not provide active thermal management; it will not replace dedicated blanking panels with specialized airflow features or fans. It is intended for standard 19" racks—non-standard or custom enclosures may require different dimensions or mounting solutions.

Key specifications

How to use

Align the panel with the 3U opening in the 19" rack and secure it to the mounting rails using the appropriate screws or cage nuts for your cabinet. Ensure the panel sits flush with neighboring equipment to maintain a continuous front surface. No special tools or configurations are required beyond standard rack-mount hardware.

What to consider before purchase

Recommendations

Install blind panels in empty rack spaces to maintain neat airflow paths and limit dust; combine with blanking panels in hot/cold aisle setups for improved airflow control.
