ROLINE 26.21.0267 is a 3 HE rack rail carrier intended for mounting IT and telecom devices in standard 19-inch enclosures. With external dimensions of 133 x 482 x 123 mm (height x width x depth) and a black finish, the carrier provides a compact, rigid support structure for servers, switches, patch panels and other rack-mountable equipment. It is designed to fit into network cabinets and open racks, simplifying alignment and fastening of devices while keeping front and rear access clear for cabling and ventilation.

Advantages

The rack rail carrier offers a precise 3 HE height that matches standard rack unit spacing and a shallow depth that suits compact equipment and small enclosures. Its steel construction and black surface treatment deliver stable mechanical support and resistance to common workshop and data centre conditions. The carrier’s fixed dimensions ensure predictable positioning of mounted devices, streamlining installation and maintenance tasks.

How to use

Secure the rack rail carrier into the 19-inch enclosure at the desired vertical position using compatible rack screws and cage nuts or threaded rails, ensuring alignment with existing mounting points. Place the equipment on the carrier and fasten it using the device’s mounting holes and appropriate hardware. Verify that there is adequate clearance for front and rear cabling and that ventilation paths are not obstructed. Periodically check fasteners for tightness, especially after equipment changes or transport.

Usage recommendations

When installing heavy or heat-generating devices, ensure the cabinet provides sufficient ventilation and use additional support brackets if required. Match the carrier’s 3 HE height with device specifications to avoid misalignment. Follow standard rack-mount safety practices and use personal protective equipment when handling sharp edges.
