The DeWalt DWST82968-1 water sealed organiser case is an improvement over the original T-Stak organiser in almost every way. By the removal of unused space within the organiser it now has a 7.8L capacity. The addition of three more removable cups mean it now holds 10. Despite the increase in capacity the case has a reduced profile. Being just 11.95cm high. Of course the organiser is also water sealed with a rating of IP54 to keep the contents of your case safe and dry.
