Features: Rolls smoothly: With repeated use, the original wheel on older, heavy wood closet doors may wear out and become stuck. These rollers maintain a consistent distance from the mounting bracket, allowing them to fit securely into the sliding groove. Replace worn rollers with these for a smooth, effortless glide—like silk. The improvement is remarkable. Easy to operate: Equipped with built-in ball bearings, these rollers operate quietly and smoothly, offering precise control over drawer movement. Made from durable ABS plastic, the roller surface provides a balanced firmness—neither too hard nor too soft—delivering excellent support. Combined with hubs constructed from solid bearing steel, they easily support the weight of the door. Ideal for repairing old kitchen drawer slides or replacing rollers in patio or stove drawers. Versatile application for various sliding mechanisms.
