E.V.A tool control system trays are designed to use in professional workshops. They use top grade aerospace quality "closed cell" EVA foam which means they will not absorb liquids, will not become tacky or sticky and can be easily clean with a pressure washer. Precision cut by CNC machinery, each cavity is purpose designed for each tool to ensure a perfect fit. The black top and vivid blue base makes it possible to instantly recognise if all tools have been returned after use.
