Columbia offers the widest range of high quality, high capacity finishing boxes in the world. From our 8" Fat Boy to our 12", they are all star performers. Well-built and fine-tuned to offer great flat joints for years. We have been told for years that our boxes are the smoothest finishing and easiest to push, and now they're also the highest capacity on the market. We are very proud to get this feedback and will make sure that every Fat Boy box we make exceeds your expectations.
