Using the DeWalt DWST08300 tool box is a breeze. First, open the auto - connect side latches and the two - piece metal wire front latches to access the tools inside. You can use the removable inner tray to separate small items from larger tools for better organization. When it comes to carrying, make sure not to exceed the 110 lbs load capacity to avoid any damage. Since it's IP65 rated, it can handle dust and water, but try not to submerge it for a long time. For maintenance, clean the box regularly with a dry or slightly damp cloth. Check the latches from time to time to ensure they're working properly. If you want to expand your storage, you can easily connect it to other TOUGHSYSTEM products.
