ROLINE 19 inch shelf 2U 350 mm depth, 25 kg load capacity model 26.21.0021

ROLINE 19" shelf 2U 350 mm depth, 25 kg load capacity (model 26.21.0021) is a fixed rack shelf designed for installation in standard 19-inch server racks and network cabinets. The shelf provides a stable, flat support surface for non-rackmountable equipment such as small servers, switches, power supplies and peripheral devices. With a compact 2U height and 350 mm depth, it optimizes space in shallow and standard-depth enclosures while offering a rated static load capacity of 25 kg.

Advantages

The shelf is constructed to offer a reliable mounting solution that simplifies equipment placement inside 19-inch racks. Its fixed design eliminates moving parts and provides consistent load distribution across the mounting points. Installation requires minimal adjustments and the shelf integrates with common rack rails, enabling orderly cable routing and accessible equipment positioning.

Suitable for

• Mounting small servers and network switches that do not have rack ears
• Placing unmounted power supplies and UPS modules
• Supporting peripheral devices such as external hard drives, modems or KVM extenders
• Creating temporary or semi-permanent storage inside server cabinets

Key specifications

• Form factor: 2U rack shelf
• Compatible rack width: 19 inches
• Depth: 350 mm
• Maximum static load capacity: 25 kg
• Mounting type: fixed shelf for rack installation

How to use

Position the shelf at the desired U height within the 19-inch rack and align the mounting holes with the rack rails. Secure the shelf using appropriate mounting screws or cage nuts compatible with the rack rails. Place equipment on the shelf ensuring the total weight does not exceed the 25 kg rating and distribute loads evenly across the surface. Route cables to minimize strain on connectors and avoid obstructing ventilation paths of adjacent devices.

Recommendations

Verify rack depth and rail spacing before installation to ensure the 350 mm shelf fits correctly. Use compatible rack fasteners and, if storing heavy or vibration-sensitive equipment, consider additional support or anchoring. Maintain a cumulative load below the specified 25 kg limit and periodically inspect mounting points for secure attachment.
