Rack blanking panel Rittal DK 7152.005, 2U, black (RAL 9005), set of 2

Rittal DK 7152.005 is a set of two 2U blanking panels in black (RAL 9005) designed to close unused rack spaces in server, network and telecom enclosures. The panels provide a flush, low-profile cover that restores a neat appearance to racks and helps direct airflow by filling empty front-mounted unit spaces. Each panel is sized for a standard 19-inch rack and supplied as a pair for simple installation where multiple adjacent units are required.

Advantages

These 2U blanking panels offer a straightforward way to reduce turbulent air recirculation inside enclosures and improve cooling efficiency by preventing bypass airflow through unused rack openings. Constructed to match the rack’s front profile and finished in RAL 9005 black, they maintain a consistent visual appearance while blocking dust and larger debris from entering the cabinet. Supplied as a set of two, they are convenient for small-scale rack adjustments without ordering individual panels.

Suitable for (tasks / use cases)

• Closing unused 2U spaces in 19-inch server and network racks
• Improving airflow management and cooling efficiency in data centres and server rooms
• Maintaining tidy rack aesthetics in telecom cabinets and IT equipment enclosures
• Temporary or permanent blocking of open rack units to reduce dust ingress

When it may not be suitable

These blanking panels are designed for standard 19-inch racks and 2U heights; they are not suitable for non-standard rack widths or for use where ventilated or perforated blanking is required for specific airflow strategies. If tool-less removable panels or integrated cable management features are required, these basic solid panels may not meet those needs.

Key specifications

• Panel height: 2U (standard rack unit height)
• Compatibility: standard 19-inch racks and cabinets
• Finish: black, RAL 9005
• Quantity: set of 2 panels
• Function: solid blanking to block unused rack spaces and reduce dust ingress

How to use

Mount the blanking panel in the chosen 2U position on the rack front using the cabinet’s standard mounting holes and compatible fasteners. Ensure the panel sits flush with adjacent equipment to maintain a continuous front profile. For best airflow results, install panels wherever there are open vertical gaps above or below active equipment to prevent air bypass and to guide cold air through server intakes. Periodically check that panels remain secure and free of accumulated dust.

What to consider before purchase

• Confirm your rack follows the standard 19-inch width and that the free space is 2U tall
• Decide whether a solid or ventilated blanking panel is required for your cooling strategy
• Verify finish colour (RAL 9005) matches or is acceptable for your installation

Usage recommendations

Install these blanking panels in a planned airflow layout: use them to fill unused 2U positions above and below active equipment to minimise recirculation and support consistent intake air delivery to servers and network devices.
