Our Retratable Warning Belt easily mounts outside your MRI suite door, visually and physically warning employees, patients and guests not to enter the MRI suite. The one-sided 2" tall belt is red with white writing, stating, "Danger! Strong Magnetic Field! Do Not Enter!" The belt is 3 meters long, or 9' 10", plenty long to visually obstruct a large double set of doors. Constructed of plastic, fabric and non-magnetic stainless steel, it is MR Conditional to 3T. Comes with mounting hardware for both belt housing and the slide in wall receiver bracket.
