Fixed 19" 1U Shelf Alantec, depth 750 mm, 4 mounting points, black

Fixed 19" 1U shelf by Alantec with a depth of 750 mm is a steel mounting shelf designed for installation in 19-inch server cabinets and racks. The shelf occupies a single unit of rack height and provides four mounting points for secure attachment to rack uprights. It is intended to hold equipment that does not require full 19" rack rails, such as small switches, routers, power supplies, UPS modules, and accessories. The black finish offers a neutral appearance suitable for data centers, server rooms, telecom closets and office rack installations.

Advantages

The steel construction ensures rigidity and load distribution across the shelf while the 750 mm depth accommodates deeper networking devices and external power units. Four mounting points increase stability and reduce risk of sagging when heavier items are installed. The 1U form factor conserves rack space compared with larger shelves and provides a simple, fixed mounting solution without moving parts or slides.

Suitable for

• Installing routers, small switches and patch panels that do not require 19" rack rail support
• Mounting UPS modules, battery packs and external power supplies
• Storing cables, accessories and peripheral equipment within a rack
• Use in server rooms, telecommunications closets and network cabinets

When it may not be suitable

This fixed shelf is not suitable for equipment that requires full 19" rack rail mounting or slide-in rail systems. It is also not intended for very heavy or vibration-sensitive devices where dedicated mounting brackets or shock-absorbing rails are required. If frequent access to devices mounted on the shelf is needed, a sliding shelf or drawer may be more appropriate.

Key specifications

• Form factor: 1U fixed shelf for 19" racks
• Material: steel
• Depth: 750 mm
• Mounting: four attachment points to rack uprights
• Finish: black

How to use

Mount the shelf at the desired 1U position in a standard 19" rack by aligning the shelf's mounting holes with the rack upright holes and fastening with appropriate rack screws and cage nuts. Place equipment centrally and distribute weight evenly across the shelf. Ensure the mounted devices do not exceed the shelf's load capacity and that cables are managed to avoid strain on connectors. For heavier items, verify rack stability and, if necessary, use additional mounting points or supports.

What to consider before purchase

• Confirm internal rack depth and available clearance to ensure 750 mm shelf depth fits
• Check the weight of intended equipment against the shelf's load-bearing capability
• Verify compatibility with your rack's hole pattern and whether cage nuts or screws are required
• Consider whether a sliding shelf or rail-mounted solution is needed for frequent access

Usage recommendations

For safe and durable installation, use appropriate rack hardware (screws and cage nuts) matching your cabinet's hole type, distribute load evenly, and secure heavy power units near the rear of the shelf to maintain rack balance. Periodically inspect mounting points for tightness and signs of wear.
