【Spring-Loaded Design】 Achieve automatic height adjustment and stability with our shock-absorbing springs. These intelligent springs ensure that the casters remain consistently in contact with the ground, providing smooth operation on both flat and uneven surfaces. The springs absorb and mitigate the shock of uneven terrain, reducing noise and enhancing your user experience.

【Durable and Long-Lasting】 Built for durability and tested for long-term performance, our spring-loaded casters use thickened galvanized steel brackets and premium TPR material. A black powder coat finish offers robust rust and corrosion resistance. Our design ensures that the casters can handle heavy loads up to 220lbs, are lightweight, heat-resistant, and impact-resistant, making them perfect for any environment.

【360-Degree Rotation】 Our spring-loaded casters provide a full 360-degree swivel, making it easy to maneuver your fence gate in any direction. This feature not only enhances mobility but also prevents the gate from sagging. By alleviating stress on the gate hardware, it extends the life of the gate posts and hinges, ensuring a longer and safer operational life.

【Multipurpose】 Designed for versatility, these 4-inch casters are ideal for various surfaces including asphalt, brick, concrete, soil, grass, and gravel. They are suitable for wooden gates, fences, and iron fences, offering reliable support and stability on uneven terrain. Ideal for long-term outdoor use, these casters provide a solid foundation for your gate's longevity.

【Installation Precautions】 To ensure smooth installation, gently compress the spring before attaching the gate wheels to prevent the gate from tilting on concave ground. For safety, install the screws towards the inside to avoid potential injuries during use. Following these simple steps will help you install the casters safely and effectively.
