Ground wire clamp

No need to write much about the design. The local hardware store provide these clamps next to the electroweld gear. This one, with the copper netting was somewhat like 5Euro. A hole for a banana jack is drilled easily... but, just have a look.

This clamp found a new home in my /p-station accessory box... BTW, the clamp ist not mounted to the paint even if it looks like in this photograph. ;-)
