Using the DeWalt DWST17814 toolbox is a breeze. First, open the heavy - duty metal latches to access the large storage area. You can place your big tools like hammers and wrenches at the bottom. Use the top - lid organizer for small items such as screws and nails, so you can find them quickly. When you need to move it, just grab the long bi - material handle. It's designed to be comfortable even if the box is full. To stack other TSTAK® modules under it, simply use the side latches to secure them in place. As for maintenance, keep it clean by wiping it down with a dry cloth regularly. Avoid exposing it to extreme temperatures or direct sunlight for long periods. If there's any rust on the metal latches, you can use a rust - remover gently. Also, make sure to close the latches properly after each use to keep your tools safe.
