Flexible cable connection for one or more cables to the rail in the same assembly.

SafePlug^® COMBI allows you to change cables at any time, switch from one cable to multiple cables, or vice versa.

SafePlug^® COMBI uses the same technology as the rest of the SafePlug® range to resist temperature changes, vibrations, and corrosion, thanks to the revolutionary cone contact connection.

The flexible cable connection system:

• Easy to change cables independently  
• Resistant to temperature changes  
• Designed for long service life  
• Resistant to vibrations  
• Sealed joint – reduces the risk of corrosion  
• Maintains high contact pressure throughout its service life  
• Stainless acid-resistant steel bolt  
• Support in the joint during installation  
• Contact cone for optimal conductivity  
• No heavy hydraulic tools required during installation

HARDLOCK Nut

HARDLOCK remains intact regardless of exposure to heat, high currents, or the strongest vibrations. Japanese railways have specified HARDLOCK for over 40 years.

In the UK, Network Rail has specified HARDLOCK for over 10 years, and new applications are constantly being added.
