Rack rail StarTech 2U fixed 19" adjustable depth, steel, black, depth 42–105.4 cm, M5

These StarTech fixed 2U rack rails provide a practical solution for mounting 19" servers and networking hardware in standard server cabinets. Constructed from steel with a black finish, the rails feature an adjustable depth range from 42 cm to 105.4 cm and accept M5 screws. Designed to convert non-rackmount devices into a 2U rackmount configuration, the rails include crossbars to cradle equipment and multiple mounting patterns to secure devices that already have mounting holes. With a compact profile that preserves adjacent rack space, these rails are suitable for retrofitting cabinets or installing deeper devices in data-centre and office racks.

Advantages

Steel construction and a black finish provide a durable mounting solution compatible with standard 19" racks. The adjustable depth range accommodates a wide variety of device depths, and the use of M5 fasteners aligns with common rack hardware standards. The design supports non-rackmount equipment by offering crossbar support and multiple attachment points, enabling secure installation without the need for a full shelf. These rails are practical for repair, retrofit and mixed-equipment environments where original manufacturer rails are unavailable.

Suitable for

• Mounting desktop servers, network switches and KVM units in a 19" rack
• Retrofitting cabinets to accept deeper or non-rackmount equipment
• Replacing damaged or missing manufacturer rails on older servers
• Data-centre and office rack installations requiring adjustable depth

How to use

Install the rails by aligning them with the front and rear rack mounting points and adjust the depth to match your equipment. Secure the rails to the rack using M5 screws at the appropriate mounting holes, then place the device on the crossbar undercarriage or attach it using the provided mounting patterns if the device has compatible holes. Ensure the rails are tightened and the equipment is supported evenly before releasing support and connecting power and network cabling.

Usage recommendations

Verify device weight and dimensions before installation and confirm compatibility with your rack's available depth. Use appropriate M5 fasteners and, where applicable, use additional attachment points to prevent movement. For heavy or irregularly shaped equipment, consider two-person handling during installation and ensure cable routing does not stress mounted devices.
