Features: Rolling smooth: Over time, the wheels on aged, heavy wooden closet doors may wear out and become stuck. These wheels maintain a consistent distance from the mounting bracket, ensuring secure fit into the sliding groove. Replace the old rollers with these for smooth, low-effort door operation. The improvement is noticeable. Easy to control: Designed with built-in ball bearings for smooth and quiet operation, enabling precise movement control. The drawer can be guided accurately to the desired position. Made of ABS plastic, the roller surface offers balanced firmness for reliable support. Combined with solid bearing steel hubs, they support the weight of the door effectively. These rollers are suitable for repairing old kitchen drawer slides or replacing rollers in patio stove drawers. They offer versatile application options.
