Features: Rolling smooth: Over time, the original wheel on some older, 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 the old rollers with these for a smooth, effortless glide—doors will slide like silk. The improvement is remarkable. Easy to control: Built-in ball bearings ensure smooth, quiet operation, similar to ice skating. You can guide the drawer precisely in the desired direction. Made of ABS plastic, the roller surface offers the ideal balance of firmness and flexibility, providing strong support. Combined with hubs made of solid bearing steel, these rollers easily support the weight of the door. Ideal for repairing old kitchen drawer slides or replacing rollers in patio or stove drawers. Versatile for multiple applications.
