Using the Knaack 31 lift-out tool tray is easy. Just place it across the top of your JOBMASTER™ Chest opening. You can put all your small tools in it, so they won't get lost and will be well - organized. When you need a tool, you can easily reach for it without digging around. As for maintenance, since it has a tan powder - coat finish, you can wipe it clean with a dry cloth regularly. Avoid using abrasive cleaners as they might damage the finish. Also, don't overload the tray beyond its capacity to ensure its long - term use. Keep it in a dry place when not in use to prevent rusting.
