## Summary description

ELKO-BIS ZK204OC is a cross terminal connector designed for use with Ø16 mm profiles or rods and four M8 fasteners. Suited for electrical grounding or mechanical junctions, it provides secure clamping and reliable electrical continuity where multiple conductors or structural elements meet. Commonly used in grounding grids, cable trays, and metal framework installations.

## Long description

ELKO-BIS ZK204OC is a terminal cross connector designed to join four elements to a Ø16 mm profile or rod using four M8 fasteners. Intended for electrical grounding and mechanical junctions, the connector ensures a stable mechanical connection and low-resistance electrical continuity between intersecting conductors or structural members. It is commonly applied in grounding grids, cable trays, and metal framework installations where a compact, cross-shaped junction is required.
Advantages
The connector offers a compact cross configuration that enables connection of four members at a single intersection while maintaining reliable clamping pressure through four M8 fastening points. Constructed to provide consistent mechanical stability and effective electrical contact, the component facilitates straightforward assembly and long-term continuity in corrosion-resistant installations when used with appropriate materials. Its geometry reduces the need for complex fitting or machining on site.
Suitable for
 Creating cross-junctions in grounding grids and earthing systems
 Joining Ø16 mm profiles or rods in cable tray supports and metal frameworks
 Mechanical fixation points where four members converge
 Applications requiring both mechanical connection and electrical continuity
When it may not be suitable
This connector is specifically sized for Ø16 mm profiles and requires M8 fastening hardware; it may not be appropriate for profiles of substantially different diameters or for applications that demand higher mechanical loads than the connector’s design allows. It is not intended to replace dedicated structural brackets for heavy-duty load-bearing constructions or for use where insulation between conductors is required.
Key specifications
 Compatible profile/rod diameter: Ø16 mm
 Fastening points: 4 × M8 thread connections
 Configuration: cross-shaped connector for four-way junctions
 Primary functions: mechanical clamping and electrical continuity
 Typical applications: grounding/earthing systems, cable trays, metal frameworks
How to use
Position the connector at the intended intersection so that each of the four Ø16 mm profiles or rods aligns with one arm of the cross. Insert the profiles into their respective clamping areas and fit M8 fasteners through the designated points. Tighten the fasteners to achieve secure mechanical clamping and reliable electrical contact, taking care to avoid over-torquing which could deform the profiles or connector. Verify continuity and mechanical stability after installation and perform any required corrosion protection or bonding checks consistent with the installation standards.
What to consider before purchase
 Confirm compatibility with Ø16 mm profiles or rods used in your installation
 Ensure M8 fastening hardware and appropriate tools are available
 Assess mechanical load requirements to verify the connector meets strength needs
 Check material and corrosion-resistance requirements for the installation environment
Usage recommendations
For reliable electrical and mechanical performance, use specified M8 hardware tightened to recommended torque values, ensure clean metal contact surfaces free of paint or oxidation, and perform a continuity test after assembly. When used in exposed or corrosive environments, consider additional protective measures such as compatible coatings or sacrificial anodes according to site standards.
