The DAKA Field Tray, has a magnetic working surface to keep your small parts organized and in one location. Made from our durable DAKA material, our Field Trays have the durability and flexibility. By simply snapping the four corners of the flat tray together, you create a walled, contained workspace that keeps your items in one enclosed area. A strong magnet retains small metallic items such as springs, bolts, pins and screws. When not in use, the Field Tray can be un-snapped for flat storage. Flat dimensions are 11.50" x 11.50", Tray dimensions are 8.75" x 8.75".
