Rittal 5326.121 freestanding 24U rack cabinet, key lock, max load 815 kg, black/grey

Rittal 5326.121 is a freestanding 24U rack cabinet designed to house servers, network switches, patch panels and associated cabling. With a two-colour finish in black and grey, it offers 24U of mounting height and a rated maximum static load capacity of 815 kg. The cabinet includes a key lock on the front door for basic physical access control and is intended for installation in server rooms, data closets and IT cabinets where stable, upright equipment mounting is required.

Advantages

The cabinet provides a compact 24U mounting space with a high load capacity suitable for dense equipment installations. Its freestanding design allows placement without the need for additional mounting structures, while the key lock increases physical security for installed devices. The black/grey finish supports integration into a variety of IT room environments. The unit is compatible with standard 19-inch rack-mounted equipment and accommodates cable management and ventilation accessories.

Suitable for

• Mounting 19-inch servers, network switches and patch panels in small to medium server rooms
• Edge and branch office IT closets where a freestanding, lockable cabinet is required
• Environments requiring a high static load capacity within a compact 24U footprint

When it may not be suitable

This 24U freestanding cabinet is not intended for very large data centre deployments where taller or multiple cabinets are required. It does not replace specialised climate-controlled racks or fully redundant enclosures designed for extreme cooling, seismic restraints or advanced access control systems. For installations that require integrated power distribution units, heavy-duty cable trays or non-standard mounting depths, verify compatibility before purchase.

Key specifications

• Mounting height: 24U
• Maximum static load capacity: 815 kg
• Form factor: freestanding 19-inch rack cabinet
• Front access: lockable front door with key lock
• Colour/finish: black and grey
• Intended use: server and network equipment, patch panels and cable management

How to use

Place the freestanding cabinet on a level, stable surface and ensure adequate clearance for ventilation and cable routing. Install 19-inch mounting rails and adjust to the appropriate depth for your equipment. Secure servers, switches and panels to the mounting rails using suitable rack screws or cage nuts. Route and organise cabling using cable management accessories to maintain airflow and serviceability. Use the key lock to restrict physical access when required and perform periodic inspections of mounting hardware and ventilation paths.

What to consider before purchase

• Verify equipment depth and rail-mounted positions to ensure compatibility with the cabinet's mounting depth
• Confirm that a 24U height and 815 kg load capacity meet current and future equipment requirements
• Check cooling and ventilation needs for installed equipment and whether additional fans or panels are required
• Consider cable management accessories and power distribution options to support your rack layout

Usage recommendations

For best results, distribute equipment weight evenly across the cabinet and mount heavier items toward the bottom. Maintain unobstructed airflow by leaving appropriate front-to-rear clearance and using cable management to prevent cable congestion. Lock the front door when equipment is unattended to provide basic physical security. If you plan to expand significantly, consider evaluating taller or multiple cabinets to accommodate future growth.
