The 4S is a large sized variant of the DRASH S series and takes a trained crew a matter of minutes to setup/take-down. The S series has a shorter width than the XB series but is slightly longer in length, both series have different lengths of tents ranging from one section to 6 sections long, giving the tent its name such as a 4S means that it is 4 sections long. This tent is large enough to fit multiple roles such as command center, housing personnel, or serve as a medical facility. We recommend using S series for standalone tents and use the XB series instead for inter-connecting. The exterior canvas skin as well as a secondary layer of white interior canvas skin called a liner is built into the frame, giving the tent a “one-piece” design, the liner’s purpose is to provide additional insulation. Electrical, plenum for air distribution, and a soft green floor can also be installed if necessary. The frame consists of advanced Titanite poles which are a fiberglass composite mix, making them very durable, light weight, and flexible.
