Rack accessory Rittal 3301.320 vertical partition / blackout panel, Black, for 210 mm width, 1915 mm height

The Rittal 3301.320 vertical partition / blackout panel is a black accessory designed to fit inside 19" server and network enclosures. It is intended for an internal width of 210 mm and a height of 1915 mm, with a panel depth of 110 mm. The panel creates a solid vertical separation between sections of the cabinet to support rack organization and to direct airflow for improved cooling efficiency.

Advantages

This vertical partition offers a straightforward way to divide cabinet interiors without modifying rack frames. Its blackout surface blocks light and visual access while supporting directed airflow management to reduce hotspot formation. The slim 110 mm depth preserves usable cabinet depth and allows installation in narrow compartments. Constructed for rack compatibility, the panel integrates with common 19" enclosures and helps maintain tidy internal cable and equipment layouts.

Suitable for

• Separating hot and cold aisles inside 19" server racks and network cabinets
• Creating dedicated compartments for PDUs, patch panels or smaller equipment within a cabinet
• Blocking light and visual access to internal cabinet areas
• Improving airflow routing to reduce hotspots and support cooling strategies

When it may not be suitable

This panel is designed for a specific internal width of 210 mm and a height of 1915 mm; it will not fit cabinets with significantly different internal dimensions. It is a solid partition rather than a ventilated panel, so if passive venting through the partition is required, a perforated or louvered alternative should be considered.

Key specifications

• Colour: black
• Type: vertical partition / blackout panel
• Intended internal width: 210 mm
• Height: 1915 mm
• Panel depth: 110 mm
• Compatibility: designed for installation in 19" server and network enclosures

How to use

Install the panel vertically inside the cabinet at the intended position, aligning it with rails or mounting points inside the 19" enclosure. Secure the panel using the manufacturer-recommended fasteners or brackets to ensure a tight fit and stable separation. Use the partition to create dedicated zones for equipment and to channel airflow from intake to exhaust paths. Verify clearance for mounted devices and cable routing after installation.

What to consider before purchase

• Confirm the cabinet's internal width is 210 mm at the installation location
• Verify available vertical space matches the 1915 mm panel height
• Ensure a solid (blackout) panel meets your airflow needs versus a ventilated option
• Check compatibility with your cabinet's mounting system and required fasteners

Usage recommendations

For effective cooling management, use the panel in combination with proper rack airflow measures: position equipment to separate hot exhausts from cold intakes, use blanking panels on unused U spaces, and verify that PDUs or cable bundles do not obstruct forced airflow paths.
