Heavy Duty Metal Ground Spikes for Robotic Lawn Mower Boundary Wire 100 Pack with Hooks for Secure Installation 100x robotic lawnmower ground spikes hooks for boundary wire nails camping<br> :<br> With additionally reinforced head and anvil and optimized geometry.<br> For attaching the cable wire in the boundary and search loop.<br> Suitable for all robotic lawnmower models from Husqvarna, Gardena, Bosch, Honda, WORX, ROBOMOW, Viking etc...<br> The head has been reinforced and an "anvil" has been added.<br> By optimizing the geometry, it is no longer possible to knock it off.<br> These hooks are more stable than the original hooks and are 100% compatible!<br> Length: approx. 9.5 cm, head: 2 cm x 1.2 cm<br> The cable no longer has to be buried, which is time-consuming:<br> It can be easily laid on the lawn and fixed tightly to the ground with nails so that the robotic lawnmower can drive over it.<br> After approx. 3 to 6 months, the cable is no longer visible because it has "grown" into the grass.<br> You also have more flexibility for optimizations (distance from the lawn edge) and possible future changes in the garden.<br> The need for hooks depends heavily on the shape of the garden:<br> On straight surfaces, one nail is needed approximately every meter. On uneven or curved terrain, consumption increases.<br> Technical data:<br> Material: plastic,<br> very stable and frost-proof,<br> Color: black,<br> Length 9 cm,<br> Head size: 2 x 1.1 cm,<br> Suitable for all common robotic lawnmower cables from e.g. Bosch, Gardena, Husqvarna, Stihl, Worx etc.,<br> Easy to attach to the ground with a rubber hammer,<br> Quantity: 100 pieces
