These are perfect for our commercial ice maker bin. The threads were the same as the previous legs. Now I can easily move it around the concrete deck for maintenance and cleaning. We have a 500 pound bin, so with the main unit, the weight of the bin, and the ice weight, it could weigh about 700 pounds. They roll and turn smoothly and the foot brakes are adjusted very well, you won't unlock them in flip flops. They work exactly as described and claimed and we don't think we'll need to replace them for the next ten years just because of constant exposure to sunlight. Hope that was helpful, thanks!
