We feared I had after delivery notice that the wire or cable receiving much is too small for the earth cable. To use the nails anyway, I have the recording slot summarily enlarged with a carpet knife. The plastic lies intersect without any major problems.
The nails holding the cable in super Earth and can be easily embarrassed. Ie shortly infected with hand and push with your foot to the desired depth in the soil.
These nails are a great thing, if you want to fix cables or wires on the lawn. Absolute buy recommendation!
