This product is made of high-quality materials with excellent rust resistance and long durability. It is designed to provide stronger traction for the robot mower on wet or sloping lawns, helping to prevent slipping and maintain optimal operation. Easy to install, it improves mowing efficiency, protects the lawn from damage, and keeps the lawn looking neat and tidy. The material offers excellent resistance and maintains a clean appearance even when exposed to moisture, soil, and other outdoor conditions over time. High tensile strength and hardness ensure the anti-slip nails resist deformation and wear under repeated pressure and friction, extending service life, reducing replacement frequency, and lowering maintenance costs. The design has been carefully calculated and tested to provide effective traction while minimizing lawn damage.Compatible with Landroid Robotic Lawn Mower models: S450i [WR101 SI], M800i [WR111MI], S300 [WR130E], S415i [WR102SI], M800i [WG757E], M500 [WR141E], M500 2.0 [WR165E], S450i [WR106SI], M900 [WG758E], M700 [WR142E], M700 2.0 [WR167E], S700i [WR101 SI], M1000i [WG796E.1], M1000 [WR143E].Color: Black Material: Plastic Note: Installation guide not included.
