The Horizontal Extrication Tool Holder, Model QM-ET-H2, is comprised of four components that can be arranged in various ways to fit virtually any cutter, spreader, or combination tool. The tool lays firmly on a flat surface, held down by gravity and secured tightly in place with a heavy-duty nylon strap. To adjust for your specific tool, simply position the base components snugly around the tools cylinder, then slide the upper components along the blades/jaws to secure them in place.
