Boxed design - All of our pouches have an interior plastic lining to give them a box shape that won't sag. Unlike other pouches that are sewn at a point, the box design keeps the pouches open, accessible and prevents tools from poking holes through the bottom. Our Professional Carpenters Triple Combo tool belt is designed from those who have worked in the industry. This beast boasts three pouches, each designed specifically to hold tools for framers and carpenters. From the tools you use to the comfort and durability, all of this has been a factor in the design of this belt. With a patented design there is no other belt like this on the market!
