Rittal SK 3311089 Steel / Zinc Steel Silver — Connection/Joining Set for Enclosures

Rittal SK 3311089 Steel / Zinc Steel Silver is a connection and joining set designed for mechanically coupling compatible Rittal enclosures and racks. Manufactured from steel and zinc-plated steel with a silver finish, the set provides alignment and secure mechanical joining between adjacent cabinets or IT racks. The components are intended for industrial and IT installation environments where durable, corrosion-resistant connections are required.

Advantages

The joining set offers a robust mechanical connection that resists corrosion due to its zinc-plated steel construction. Its silver finish maintains a consistent appearance when mounted alongside matching enclosures. Supplied in a multi-piece pack, the set supports multiple joining points and facilitates repeatable alignment of adjacent cabinets and rack sections during installation.

Suitable for

• Joining adjacent Rittal enclosures or TS IT rack sections
• Industrial switchgear and control cabinet installations
• IT and server room rack alignment and mechanical coupling
• Environments requiring durable, corrosion-resistant enclosure connections

When it may not be suitable

This joining set is intended for mechanical alignment and connection of compatible enclosure and rack profiles; it does not provide electrical bonding, sealing against water ingress, or vibration isolation by itself. If an application requires integrated electrical earthing, IP-rated gasket sealing, or specific anti-vibration mounting, additional components or alternative products should be considered.

Key specifications

• Material: Steel and zinc-plated steel for corrosion resistance
• Finish: Silver
• Pack quantity: 24 pieces
• Pack weight: 550 g (approximate)
• Application: Mechanical joining and alignment of compatible enclosures and racks

How to use

Align the mating edges of the adjacent enclosures or rack sections so that the joining set components match the corresponding mounting points. Insert and secure the supplied joining elements according to the enclosure manufacturer’s assembly instructions, ensuring all fasteners are tightened to the recommended torque. Verify mechanical alignment and stability after installation and repeat for each joining position as required.

What to consider before purchase

• Confirm physical compatibility with the specific Rittal enclosure or TS IT rack profiles to be joined
• Determine whether additional components (earthing straps, gaskets, or vibration mounts) are required for the installation
• Verify the required quantity of joining sets based on the number of cabinets or rack sections to be connected
• Check environmental conditions to ensure zinc-plated steel is suitable for corrosion protection

Usage recommendations

Use the joining set during initial cabinet placement for best alignment results and perform a final inspection of mechanical tightness after any cabinet relocation. For electrical continuity or environmental sealing, install the appropriate complementary accessories recommended for Rittal enclosures.
