TRACKTUBES™ are a high quality, anodized aluminum extrusion with integrated T-tracks. They were originally designed to be used with sawhorses, but have many other uses, both in and out of your shop.  Perfect for setting up a multi-function work station, used as router sled rails, or built into a workbench with DIY telescoping extensions for material support.  These are only a few examples of how Woodworkers, DIYers, and other Makers are using TRACKTUBES™.
