## Summary description

Mechanical coupling M22 HiSmart EL240210 designed for connecting an earth rod with 20 mm diameter. Provides threaded M22 connection for secure mechanical and electrical continuity in grounding systems. Suitable for installation in outdoor and indoor earthing applications where a reliable joint between rods or conductor segments is required.

## Long description

Coupling M22 HiSmart EL240210 is a mechanical coupling designed for connecting earth rods with a 20 mm diameter. Made from a high-strength copper alloy (brass), the coupling provides a threaded M22 connection that ensures secure mechanical joining and electrical continuity in grounding and lightning protection systems. The screw-type connection allows extending rod length by joining rods, or connecting a rod to a driving head without damaging the rod thread.
Advantages
The coupling is manufactured from brass, which offers good mechanical strength and resistance to corrosion when buried, helping to protect the ground rod thread and prolong service life. Threaded screw connection (M22) provides reliable mechanical and electrical contact. Compact dimensions and a straightforward installation process make it suitable for in-field earthing work.
Suitable for
Connecting two earth rods (rod-to-rod)
Joining a rod to a driving head
Extending grounding rod length in earthing systems
Use in grounding and lightning protection installations, indoor and outdoor
