The TK-4 Tourniquet features a newly developed woven elastic textile band (2” wide by 40” long) that provides incredible strength and flexibility. With one steel hook fastened steadfast (three thick hog rings per S-Hook) to both ends of the elastic band, and packaged in a small sealed pouch, TK-4 is ideal for applying direct pressure over a wound or for creating pressure on an extremity to reduce blood loss.
