Introducing the T-Track 3x3 Intersection Kit by POWERTEC. This handy t-track kit was designed to help you build and optimize your workbench, drill press, jigs and fixtures. They work effectively by allowing you to secure your work material in a variety of worktable configurations. Each of the four included aluminum pieces is 1-1/2 in. long and cut at 90°. All together, they form two perpendicular tracks, or one intersection measuring at 3x3 in. Once assembled, you can easily slide your jigs back and forth - configuring your t-track components, such as clamps, hold-downs, stops and more, in most every direction required by your project at hand. Along with your creative vision, the possibilities are almost limitless. High Quality Profile: The tracks are precision-machined with a premium look and feel, flaunting a burr free design with good clean miters. Each piece has 2-drilled and countersunk holes (11/64 in. diameter) quick and easy mounting. Additionally, they are designed to set flush to the table for optimal functionality - working seamlessly with your clamps, t-bolts and knobs. Our t-tracks are constructed out of lightweight anodized aluminum and offer optimal performance with long-term durability. Compatibility: This intersection kit is designed to work with the standard POWERTEC T-Tracks (Item 71378, 24 in. T-Track, Item 71379, 48 in. T-Track).
