Quick installation: The spike set with 100 cable spikes for robotic lawnmowers can be driven into the ground quickly and safely thanks to the spikes' wide and solid striking surface. We recommend using a rubber mallet. The mower stake tip can be firmly inserted into the ground. Perfect fit: The notches on our pegs fit perfectly and do not slip. The wire can be attached to the robotic lawnmower stake with the long hook. Works with all major brands: Use our boundary stakes to connect all common robotic lawnmower wires.
