Rack shelf EFB Elektronik 19 inch 0,5U

In a busy server room, a network technician needs to mount a non-rack-mountable UPS and a small switch without wasting vertical space. This fixed shelf from EFB Elektronik slides into any standard 19-inch rack, taking up only half a unit of height while providing a stable, load-bearing platform for equipment up to 70 kg. Its 950 mm depth extends into the cabinet, making it ideal for deep racks, and the black powder-coated steel blends seamlessly with existing infrastructure.

Key specifications

• Rack compatibility: 19-inch, EIA-310-D compliant
• Rack units: 0.5U (height 22 mm)
• Width: 482.6 mm
• Depth: 950 mm (mounting depth min 950 mm, max 1050 mm)

• Ventilation: Non-ventilated (solid)

Why choose it

This shelf is built for heavy-duty use. The robust steel construction resists deformation even under maximum load, and the protective black coating prevents corrosion and scratches. Its half-unit profile frees up valuable rack space for other components, while the generous depth accommodates deep equipment or cable bundles. The fixed design ensures stability, eliminating any movement or vibration that could affect sensitive devices.

Ideal use cases

• Mounting small UPS units, power supplies, or network appliances that lack rack ears
• Organizing patch panels, cable management elements, or storage drives
• Placing routers, monitoring equipment, or KVM switches that require a stable platform
• Supporting heavy equipment in deep server cabinets (up to 1200 mm cabinet depth)

Good to know

The shelf is designed for front mounting only and includes all necessary screws and cage nuts for installation (screws included: yes, cage nuts included: yes). It is not ventilated, so it is best suited for equipment that does not require airflow from below. The product is compliant with EIA-310-D standards, ensuring compatibility with all standard 19-inch racks. Package dimensions and weight are provided for logistics planning.
