Rack shelf Extralink SHELF 1U for 19" wall cabinets, 1U, 300 mm, black, metal

Extralink SHELF 1U is a metal rack shelf engineered for 19" wall cabinets. With a 1U height and 300 mm depth, this black shelf fits standard 19" (48.3 cm) rack rails and provides a stable platform for non-rackable devices and accessories inside wall-mounted cabinets. It is intended to maximize usable space and support orderly cable routing within confined cabinet installations.

Advantages

The shelf is made of durable metal with a black finish that resists wear in typical server room and telecommunications environments. Its 1U form factor preserves vertical rack space while offering a flat load-bearing surface for small switches, patch panels, power supplies, or tools. Compatibility with standard 19" rails ensures straightforward installation and reliable support for equipment that does not include rack ears.

Suitable for

• Mounting non-rackable networking equipment such as small switches and media converters
• Holding patch panels, power adaptors or cable management accessories
• Organizing tools, labels and spare parts inside wall-mounted cabinets
• Creating a stable surface for monitoring or test devices in server closets

Key specifications

• Form factor: 1U rack shelf
• Compatibility: standard 19" rack rails (48.3 cm)
• Depth: 300 mm
• Material: metal

How to use

Install the shelf by aligning it with the 19" wall cabinet rails and fastening it at the desired 1U position using appropriate rack screws or mounting hardware. Place non-rackable devices centrally on the shelf to distribute weight evenly and route cables through existing cable entry points or along the cabinet sides to maintain tidy cable management. Periodically check fastenings to ensure the shelf remains secure under load.

Usage recommendations

Ensure the combined weight of equipment and accessories does not exceed the load capacity of the cabinet rails; use centered placement and avoid overhang. For devices generating heat, allow sufficient airflow around the shelf and consider positioning heat-producing equipment near ventilation openings. Use anti-slip pads or Velcro straps for added retention when mounting lightweight or vibration-prone items.
