1U Rack Shelf ProBase FS-1U-35 — 350mm depth, front and rear mounts, fits 200–500mm cabinet depth

ProBase FS-1U-35 is a 1U rack shelf with a fixed 350 mm depth designed for installation using both front and rear mounting points. It fits 19-inch server racks and network cabinets with depths from 200 to 500 mm, offering a stable support surface for small equipment, peripherals, and cable routing inside compact enclosures. The shelf enables straightforward integration into standard rack systems and improves accessibility for devices that do not require full-height mounting.

Advantages

The shelf provides a robust metal platform with even load distribution across the mounting rails, minimizing sag in confined rack spaces. Dual front-and-rear mounting increases stability and makes the shelf suitable for uneven cabinet depths. Its fixed 350 mm depth is optimized for common small devices and cable bundles while ensuring consistent airflow and access to rear connectors. The compact 1U height preserves vertical rack space for additional modules or equipment.

Suitable for

• Mounting small network switches, routers and patch panels that do not require full rack ears
• Placing external drives, power supplies or compact UPS units
• Organizing cable bundles, patch cords and simple cable management accessories
• Holding monitoring or control devices, modems and small peripherals inside a 19-inch cabinet

Key specifications

• Form factor: 1U rack shelf for 19-inch enclosures
• Depth: fixed 350 mm usable surface
• Mounting: supports both front and rear mounting points for cabinets 200–500 mm deep
• Material: rigid metal construction for stable load support
• Finish: protective coating for corrosion resistance and durable surface
• Weight capacity: designed for light to medium loads typical for peripherals and cable bundles

How to use

Install the shelf into a 19-inch cabinet by aligning the front mounting flanges with the desired U position on the rack rails, then extend the rear support to the cabinet rear mounting points and fasten with appropriate rack screws. Ensure the cabinet depth is within the supported 200–500 mm range so that both front and rear mounts engage. Place devices centrally on the shelf to balance weight and leave space for airflow around power and network connectors. Use standard rack hardware and tighten fasteners to secure the shelf before adding equipment.

Usage recommendations

For reliable operation, distribute load evenly and avoid concentrating heavy equipment on one side. Reserve the shelf for devices and accessories that match the 350 mm depth to prevent overhang. If heavier items are required, check the cabinet and shelf load ratings and consider additional support or a deeper shelf solution.
