Set it. Clamp it. Cut it.The NGX Clamp Edge SystemTM makes it faster and simpler to break down sheet material and rip boards with clean, accurate cuts every time. It's never been easier to rip, cut, and break down material than with the all-new NGX Clamp EdgeTM System. No more fumbling with adjustable clamp ends on opposite sides of the straight edge - the adjustable clamp is connected to the handle. Simply hook the Clamp Edge across your board, line it up with your cut, and clamp it down - all without moving your feet. Here's why PTIA likes the NGX Clamp EdgeTM System so much: "Track saws are gaining popularity thanks to the number of cuts they can replace a table saw on. That trend isn't lost on the Bora Tool crew and their new NGX Clamp Edge Saw Guide helps transform your current circular saw into an accurate-cutting track. While this isn't a brand new idea for Bora Tool, they've made this update their easiest to use so far. Easier use means you're more likely to use it and finish with higher-quality results."
