The grounding clamp is working very accurately, stable and easy to assemble. The seat of the clamp on poles is very firm after tightening the clamping screw. The clamp can be a fixed installation of two ground conductors in two directions (horizontally and vertically) zu.Den biggest advantage I see in the fact that stainless steel is used for all parts. That should guarantee a long-term use without corrosion, yes for the electrical conductivity is a crucial factor.
