Using the DeWalt DWST08035 TOUGHSYSTEM 2.0 Compact Deep Toolbox is easy. First, you can use the lidded organizer and the 4 removable dividers to sort your tools neatly inside. The auto - connect side latches let you quickly link it to other TOUGHSYSTEM 2.0 toolboxes. You can hang power tools and accessories on the built - in side - handles with a tool belt hook. For identification, use the customizable content plate to label what's inside. When it comes to maintenance, since it's water - resistant (IP65), you don't have to worry too much about a little water. But try to keep it away from long - term exposure to extreme conditions. After each use, just wipe it down with a clean cloth. Also, check the metal - wire front latches and bi - material carry handle regularly to make sure they're in good condition.
