Features: Rolling smooth: Over time, the original wheel on some aged, heavy wood closet doors may wear out and become stuck. These wheels maintain a consistent space from the mounting bracket, allowing them to fit securely into the sliding groove. Replace old rollers with these for smooth, effortless movement — the improvement is remarkable. Easy to control: Equipped with built-in ball bearings, they operate quietly and smoothly, offering precise control over the drawer's movement. Made from durable ABS plastic, the roller surface provides a balanced firmness, offering excellent support. Combined with hubs constructed from solid bearing steel, these rollers can easily support the weight of the door. Ideal for repairing older kitchen drawer slides or replacing rollers in patio or stove drawers. Suitable for various applications.
