Renkforce RF-7112942 19-inch Rack Shelf, 1U, Extendable, for Cabinets from 500 mm Depth, Black

The Renkforce RF-7112942 is a professional-grade 19-inch rack shelf designed to optimize space and accessibility within server cabinets. Occupying only 1U of rack space, this extendable shelf provides a reliable and stable mounting surface for IT equipment that is not natively rack-mountable. Its robust construction and pull-out mechanism allow for seamless integration into various network environments, ensuring that hardware remains secure while remaining easily accessible for maintenance or configuration changes.

Advantages

This rack shelf offers significant benefits for data center management and home network organization. The primary advantage is its extendable design, which allows users to pull the shelf out for quick access to cables, ports, or device controls without needing to remove the equipment from the rack. The 1U height ensures minimal vertical space consumption, leaving more room for other critical components. Furthermore, the durable black finish provides a sleek, professional appearance that matches standard server cabinet aesthetics, while the sturdy build quality ensures long-term reliability for heavy-duty hardware.

Suitable for

• Supporting non-rack-mountable servers or network switches
• Housing external hard drives and backup storage devices
• Organizing routers, modems, and power distribution units
• Providing a temporary workspace for diagnostic tools during maintenance

When it may not be suitable

This shelf is not suitable for cabinets with a depth of less than 500 mm, as the mounting rails require a minimum depth to be installed correctly. Additionally, it is not designed to support equipment that exceeds the maximum load capacity specified for the shelf, nor is it intended for use in open-frame racks that lack the necessary side-mounting support points.

Key specifications

• Form factor: 19-inch rack mount
• Height: 1U
• Compatibility: Cabinets with a minimum depth of 500 mm
• Mechanism: Extendable/Pull-out
• Color: Black

How to use

To install the shelf, align the mounting brackets with the vertical rails of your 19-inch server cabinet at the desired height. Secure the brackets using standard rack screws and cage nuts. Once the frame is firmly attached to the cabinet rails, ensure the sliding mechanism moves smoothly. Place your equipment onto the shelf, ensuring the weight is evenly distributed. To access the hardware, simply pull the shelf forward using the front handle until it reaches its extension limit.

What to consider before purchase

• Verify the internal depth of your server cabinet is at least 500 mm
• Check the total weight of your equipment to ensure it stays within the shelf's load limits
• Confirm that you have 1U of available vertical space in your rack
• Ensure there is sufficient clearance in front of the cabinet to allow the shelf to extend fully

Usage recommendations: Always distribute the weight of your equipment evenly across the surface of the shelf to prevent sagging or mechanical strain on the sliding rails. Regularly inspect the mounting screws to ensure they remain tight, especially if the shelf is frequently extended.
