Cable duct / cable trough Rittal DK 7111.212 Black, 1U mounting, set of 10

The Rittal DK 7111.212 single cable bracket provides a 1U (44.45 mm) vertical or horizontal cable guide inside enclosures and distribution levels. It allows baying of units by inserting supplied connecting pieces between two bracket elements to form an additional guide chamber. Each bracket can be opened and closed independently using a turning catch, enabling organized routing of whole cable bundles and later reconfiguration. The support element is made of sheet steel with a spray finish; feed brackets, connecting pieces and turning catches are plastic.

Advantages

The design offers a full 1U height for U-related cable entry of entire cable bundles and permits simple expansion of existing units by baying with included connecting pieces. Individual brackets are operable independently via turning catches, which simplifies installation, re-routing and maintenance without disassembling adjacent guides. Materials combine sheet steel support for strength with plastic brackets and catches for flexible operation.

Suitable for

• Routing and organizing horizontal and vertical cable runs inside server racks and enclosures
• Expanding existing rack-mounted cable management by baying additional bracket elements
• Managing whole cable bundles where a full 1U feed opening is required
• Environments where selective opening of individual cable guides is needed for maintenance or changes

When it may not be suitable

This single cable bracket is intended for standard 19-inch rack enclosures and distribution levels; it may not be suitable for non-standard or custom cabinet geometries where 1U height or mounting points differ. It is not designed as a sealed or dustproof cable entry solution and lacks integrated strain-relief hardware for specific cable types.

Key specifications

• Bracket height: approx. 1U (44.45 mm)
• Material (support): sheet steel with spray finish
• Material (brackets, connecting pieces, turning catches): plastic
• Function: horizontal and vertical cable guiding; baying via connecting piece to create additional guide chamber
• Operation: individually openable and closable cable brackets with turning catch

How to use

Mount the bracket into the rack or enclosure at the desired 1U position. To bay and extend cable guides, insert the supplied connecting piece between two bracket elements to form the additional guide chamber. Open individual bracket elements using the turning catch to feed cable bundles through the U-shaped guide, then close the catch to secure routing. Repeat opening and closing as needed to add, remove or reorganize cables.

What to consider before purchase

• Confirm compatibility with your rack or enclosure mounting style and available 1U positions
• Assess whether a non-sealed, open cable guide meets your environmental and strain-relief requirements
• Determine the expected size and quantity of cable bundles to ensure a 1U feed is sufficient

Usage recommendations

For best results, plan cable routes before installation, use the turning catches to open only the sections needed, and combine multiple bracket elements with the included connecting pieces to create continuous guides while preserving easy access for maintenance.
