Ground spikes for robotic lawnmowers: The robotic lawnmower set contains 100 ground spikes. Each ground spike is 8.5 cm long and is used to attach the boundary wire of the robotic lawnmower to the lawn. The boundary wire can be easily attached with the hook, which is indispensable for all robot owners. Fast compatibilityThe ground hook is suitable for wire diameters from 0.1 to 3.8 mm, universally applicable, suitable for Gardena, Husqvarna, Worx, Bosch, AL-KO, Robomow, McCulloch Stiga, Wolf Garten, etc. High-quality materials: Our high-quality ground spikes are made of extremely strong and durable plastic and are durable. This makes the ground spikes extremely stable and durable and will not break, even when the wire is pulled hard. The ground spikes can be firmly attached to the ground. Quick installation: Simply hang the boundary wire on the hook-shaped head of the ground spike. The hook-shaped design ensures that the ground spike does not slip. Thanks to the strong and large hammer surface of the ground spike, it can be driven into the ground quickly and safely. We recommend using a rubber mallet to secure it easily and securely. The unique pointed design makes it easy to drive into the ground. Weatherproof: The robotic lawnmower's hook is resistant to various weather conditions such as rain, frost, and sun. This ensures maximum durability of the hook.
