Heavy Duty Gate Caster, Spring Loaded Gate Wheel, Swivel Caster Wheels for Wooden Gate and Fence 250LBS Load Capacity 4 Inches Rubber Wheel (Black, 1)

Built-in Spring: The unique built-in spring design not only prevents sand and stones from entering the spring, causing damage and scratches, but also reduces the impact of rain and sunlight on the spring, thereby extending its lifespan.

Shock Absorption: The spring can extend up to 1.73 inches, which helps effectively support the door and evenly distribute the load on the door. At the same time, it allows the wheel to move smoothly on uneven ground. Please note that it cannot be used on very deep pits or extremely uneven surfaces.

Note: To prevent the door panel from hanging when the wheel encounters a recessed area, it is necessary to compress the door wheel spring in advance during installation. This ensures that when the door wheel moves into the recessed area, the wheel can still support the door body.

Structural Stability: The sturdy structure is achieved through a combination of thick galvanized steel brackets and high-quality rubber wheels. This braked door wheel can perfectly support doors or fences up to 250 lbs per wheel. The ball bearings in the door wheel allow you to easily adjust the moving direction.
