Supporto per guida DIN ROLINE 19 pollici 4U, acciaio, grigio (modello 26.21.0112)

The ROLINE 19-inch top-hat rail support 4 U is a steel mounting bracket for installing H-profile (top-hat) rails in 19" enclosures and server racks. Finished in grey, the support is designed for a 390 mm wide top-hat rail and includes a 40 x 35 mm rear opening that functions as a cable duct for routing cables neatly behind mounted rails.

Advantages

This steel support provides a sturdy and stable attachment point for top-hat rails in network cabinets and telecom housings, helping to secure rails and the equipment mounted on them. The grey finish offers a neutral appearance that integrates with common rack interiors, while the integrated rear cable duct simplifies cable management and reduces clutter behind mounted devices.

Suitable for

• Mounting H-profile/top-hat rails inside 19" server cabinets and racks
• Server rooms, network closets and telecom cabinets
• Situations requiring a dedicated cable duct behind mounted rails

When it may not be suitable

This support is intended for use with top-hat rails of a specific width and for installation in 19" enclosures; it may not fit non-standard or custom rack systems or cabinets with different internal widths. It does not include rail sections themselves or additional mounting hardware beyond the support bracket, so additional components may be required to complete a rail installation.

Key specifications

• Material: steel
• Height: 4 U
• Colour/finish: grey
• Compatible rail width: 390 mm top-hat rail
• Rear cable duct opening: 40 x 35 mm

How to use

Position the support bracket inside the 19" enclosure at the desired vertical location and secure it to the rack mounting points. Attach the top-hat rail to the support, ensuring the rail aligns with the bracket and is fastened firmly. Route cables through the 40 x 35 mm rear opening to keep them organized behind the rail, and verify all fastenings are tightened to provide secure support for mounted equipment.

What to consider before purchase

• Confirm the internal width and mounting pattern of your 19" enclosure to ensure compatibility with a 390 mm top-hat rail support.
• Check whether additional rail sections, fasteners or accessories are required to complete the installation.
• Ensure a 4 U height meets your intended vertical space and mounting needs.

Recommendations

For reliable installation, use suitable rack fasteners and tighten all connections to manufacturer-recommended torque. Route cables through the rear duct to maintain airflow and prevent strain on connections.
