Rack shelf Stalflex S-RSA19-1U-350B 19" 1U 350 mm black

Stalflex S-RSA19-1U-350B is a 19" 1U rack shelf with a 350 mm depth finished in black, designed to support non-rackable equipment, accessories and small devices inside standard 19-inch server cabinets and racks. The shelf occupies a single 1U mounting unit and provides a flat, stable surface for routers, switches, external drives, power supplies and other components that cannot be mounted directly to vertical rails. Its compact depth helps optimize space in network, telecom and server room installations while keeping cabling and devices accessible.

Advantages

The shelf offers a simple installation process that fits standard 1U mounting positions and includes mounting points aligned to 19-inch rack rails. Constructed with a robust metal platform and finished in black, it gives reliable load support and resists surface wear. Its shallow 350 mm depth is suitable for tight rack spaces where deeper shelves would reduce usable clearance, and the flat design enables flexible placement of a variety of small equipment without special brackets.

Suitable for

• Placement of non-rackable network devices such as small routers, switches and modems
• Support for external hard drives, UPS accessories and power distribution modules
• Temporary staging of equipment during maintenance or configuration tasks
• Cable organizers, patch panels and accessory trays that do not require rail-mounting

Key specifications

• Form factor: 19-inch, 1U height
• Depth: 350 mm
• Finish: black protective coating
• Material: metal platform for stable weight support
• Mounting: compatible with standard 19" rack rails and 1U mounting spacing
• Surface: flat platform suitable for various small devices

How to use

Install the shelf by aligning its mounting holes with the 19" rack vertical rails at the chosen 1U position and secure it using appropriate rack screws and cage nuts for your cabinet. Place devices and accessories on the flat surface, ensuring weight is distributed evenly and does not exceed the cabinet or rail load limits. Route cables to avoid obstructing airflow and to maintain access to front and rear ports. For temporary staging, use the shelf to hold equipment during configuration or replacement, then remove or reposition as needed.

Usage recommendations

Verify the weight of placed equipment and the load capacity of the server rack before use. Use suitable mounting hardware for your specific rack type and ensure proper cable management to maintain airflow and serviceability.
