This set of four casters was purchased to replace the wheels I had previously fitted to my steel shelf cart. The previous set of coasters was purchased at a truck tool store. The rubber on these reels is thicker and shinier. Unlike the ones I've replaced, they spin easily under a full load and roll on my garage floor without dragging or binding. They are equipped with high-quality roller bearings and roll smoothly. These little wheels also have a strong locking mechanism and hold the shelf firmly. At this price I can afford to replace more of my shelves or tool stands and carts.
