Freestanding rack cabinet Rittal 5307.157 42U, key lock, black/grey, 357 kg max load

The Rittal 5307.157 freestanding 42U rack cabinet is designed for installation of servers, networking devices and related IT equipment in server rooms, data centers and network closets. Its upright 42U layout allows efficient vertical mounting of standard 19-inch devices while offering a keyed lock for controlled physical access. The cabinet’s two-tone black and grey finish provides a neutral appearance suitable for professional environments, and the construction supports a considerable static load for consolidated equipment installations.

Advantages

The cabinet provides a standardized 42U mounting space compatible with 19-inch rack equipment, combined with a keyed locking mechanism to restrict unauthorized access. Its freestanding design enables placement in server rooms or network closets without the need for permanent wall mounting. The two-tone finish helps conceal dust and fits common IT room aesthetics, and the specified static load capacity supports dense equipment configurations within the rack.

Suitable for

• Mounting rack servers, switches and patch panels in server rooms or data centers
• Consolidating network equipment in telecom or network closets
• Small to medium-sized IT environments that require secure, vertical equipment organization
• Environments needing a freestanding cabinet with a keyed lock for controlled access

When it may not be suitable

This cabinet may not be suitable when equipment weight or cooling requirements exceed its static load capacity or passive ventilation capability. For deployments requiring active cooling integration, seismic anchoring, or space-optimized shallow-depth racks, alternative enclosures with dedicated airflow management or mounting features might be more appropriate.

Key specifications

• Rack height: 42U
• Form factor: freestanding cabinet for 19-inch rack equipment
• Access control: keyed lock on the door
• Finish: two-tone black and grey
• Maximum static load capacity: 357 kg

How to use

Position the cabinet on a level surface and allow sufficient clearance for front and rear access and cable routing. Install heat-producing devices following standard rack-mounting procedures, using appropriate mounting rails and cage nuts where required. Distribute equipment weight evenly across the vertical mounting posts and avoid exceeding the specified static load capacity. Use the keyed lock to restrict physical access and route cables through existing entry points or accessory cable management solutions to maintain orderly cabling.

What to consider before purchase

• Confirm that the 42U height and internal depth suit the physical dimensions of your rack equipment
• Verify cumulative equipment weight to ensure it does not exceed the 357 kg static load limit
• Assess cooling needs and determine whether additional ventilation or active cooling will be required
• Check access and space constraints where the freestanding cabinet will be located

Usage recommendations

For reliable operation, mount heavier devices toward the bottom of the cabinet, plan airflow paths from front to rear for equipment that requires front-to-back cooling, and secure cabling with proper management accessories. Periodically inspect the locking mechanism and structural fittings to ensure long-term stability and security.
