Stable support and durable construction: The trimmer support wheels use a triangle design to provide a stable base. Made from polyethylene, they resist rust and corrosion and are built for long service. They deliver strong support to your mower and stay more stable than typical Twheel designs. Universal compatibility: Fits standard 2528 mm trimmer wheels and is suitable for most mowers and string trimmers on the market. Labor saving and efficiency: Although small, these wheels stabilize the tool and reduce user effort, helping you work longer with less fatigue and improving overall efficiency. Adjustable for different conditions: The height can be tuned to match your terrain, making trimming easier on slopes, uneven ground, yards, and tight spaces like narrow corners. Use scenarios: Mowing on a steep slope where extra stability matters Trimming along fences, walls, or under low branches Navigating narrow garden beds and edge lines
