19-inch shelf ROLINE 26.21.0281, 1U, 250 mm depth, 15 kg load capacity, grey

ROLINE 26.21.0281 is a 19-inch 1U rack shelf with a 250 mm depth and a grey finish, designed to provide a stable support platform inside standard 19" server cabinets and network racks. The shelf accepts non-rackmount devices, peripherals and accessories, allowing neat organisation of equipment that cannot be mounted directly in rack rails. Its compact 1U height saves vertical space while offering a flat surface for various IT and AV components.

Advantages

The shelf combines a low-profile 1U form factor with a 250 mm usable depth, providing a balance between space efficiency and load capacity. With a rated load capacity of 15 kg it is suitable for many lightweight devices while remaining easy to install in standard 19" enclosures. The grey finish offers neutral appearance that integrates with most rack interiors and reduces visual clutter. The rigid construction prevents sagging and maintains stability for equipment placed on the shelf.

Suitable for

• Small non-rackmount servers and mini PCs
• External hard drives, NAS enclosures and storage devices
• Network peripherals such as modems, switches or power strips
• AV equipment, set-top boxes and media players
• Tools, adapters and spare parts inside a cabinet

Key specifications

• Form factor: 19-inch, 1U height
• Depth: 250 mm usable depth
• Load capacity: 15 kg maximum
• Finish: grey
• Mounting: fits standard 19" rack rails

How to use

Install the shelf by aligning it with two adjacent 19" rack rails at the desired height and secure it using standard cage nuts and screws or the cabinet's threaded rails, depending on the rack type. Place devices centrally on the shelf to distribute weight evenly and avoid exceeding the 15 kg limit. Route cables neatly behind or beneath the shelf to maintain airflow and access to front and rear panel connections. Periodically check fasteners for tightness if the cabinet is subject to vibration or frequent adjustments.

Usage recommendations

Position heavier items as close to the rack's vertical mounting rails as possible, and avoid placing high-heat-generating equipment directly on the shelf without adequate ventilation. For equipment heavier than the shelf's rated capacity, consider a deeper or reinforced mounting solution.
