Using the DeWalt DWST17809 TSTAK Open Tote is a breeze. First, unfold the handle when you're ready to carry it. You can put all sorts of tools or items inside the large interior space. If you have other TSTAK® family modules, use the side latches to connect them together. When it comes to the XP™ tape measure, just pull it out when you need to measure something. Remember, it can handle a 60 - foot drop, but try not to test it too often. For the lanyard slot, you can attach a lanyard for extra security when you're on the move. As for maintenance, keep it clean by wiping it with a damp cloth from time to time. Avoid exposing it to extreme temperatures or harsh chemicals to ensure it lasts a long time.
