Rack blanking panel 19" 4U Delta Z19-4U*P2, pack of 2

Delta 19" 4U blanking panels (pack of 2) are designed to fill unused 4U spaces in standard 19-inch server racks and cabinets. These panels create a uniform front appearance, help maintain proper airflow paths inside the cabinet and reduce the amount of dust and debris entering the enclosure. Supplied as a pair, the panels are intended for quick installation in data centres, telecom racks and server enclosures where modular blanking and airflow management are required.

Advantages

These 4U blanking panels provide an easy way to close unused rack spaces without modifying existing equipment. By directing airflow through active equipment rather than empty bays, they contribute to more efficient cooling and can help maintain stable operating temperatures. The panels also minimise dust ingress and improve the visual organisation of racks, making maintenance and inventory management clearer.

Suitable for

• Data centre and server room racks
• Telecommunications cabinets and network enclosures
• Equipment racks in labs, test rooms and control cabinets
• Retrofitting or reorganising rack layouts with unused 4U spaces

Key specifications

• Size: fits standard 19-inch rack mounting width
• Height: occupies 4U of rack space
• Quantity: pack of two blanking panels
• Material: durable sheet designed for rack use (metal or coated steel)
• Finish: coated surface for corrosion resistance and easy cleaning

How to use

Install each blanking panel into a vacant 4U position in a 19-inch rack using standard rack screws or captive mounting hardware. Align the panel with the rack’s mounting rails and secure it to eliminate gaps around the opening. Ensure panels are placed to direct cooled airflow through active equipment and to block open vertical or horizontal pathways that would bypass installed devices.

Usage recommendations

Place blanking panels above and below active equipment to create a continuous airflow path, and replace or reposition panels whenever rack layout changes. Regularly inspect panels for secure fastening and surface condition as part of routine cabinet maintenance.
