Rack shelf LANBERG 19" 1U 483 x 500 mm, load capacity up to 25 kg, 4-point mounting

LANBERG 19" 1U rack shelf with dimensions 483 x 500 mm provides a compact, sturdy platform for mounting non-rackable equipment in 19-inch server racks. The shelf is constructed from steel and is designed for 4-point mounting into standard 19" rails at 1U height. It supports items up to 25 kg and is suitable for organizing peripherals, small switches, modems, power supplies or tools inside server cabinets and network enclosures.

Advantages

The steel construction ensures durability and consistent load distribution across the shelf surface. Four-point mounting gives stable attachment to 19" rack rails, reducing vibration and movement of equipment. Its 1U height and 483 x 500 mm footprint make it space-efficient while offering enough depth for most compact devices. The shelf’s rated load capacity of up to 25 kg allows secure placement of heavier peripherals without dedicated rack ears.

Suitable for

• Mounting small switches and unmanaged network devices
• Holding modems, routers and power supplies inside a rack
• Placing external hard drives, UPS batteries or tool kits
• Temporary placement of equipment during maintenance or testing

Key specifications

• Form factor: 1U shelf for 19" racks
• External dimensions: 483 x 500 mm (width x depth)
• Mounting type: 4-point attachment to 19" rack rails
• Material: steel construction for rigidity
• Load capacity: up to 25 kg

How to use

Install the shelf by aligning its mounting holes with the chosen 1U position on the 19" rack rails and secure it using appropriate rack screws and cage nuts for four attachment points. Place equipment centrally on the shelf to balance the load and avoid overhanging that could reduce stability. For devices with cables, route and secure cabling to prevent strain on connectors. Verify that the combined weight of mounted items does not exceed the specified 25 kg limit.

Usage recommendations

For reliable performance, use compatible rack fasteners and check that the rack rails and cage nuts are rated for the applied load. Distribute weight evenly and avoid concentrated heavy loads near the front edge. Consider additional support or a fixed rack-mount tray for appliances exceeding the shelf’s load rating or for long-term permanent installations.
