A practical and robust system for the immobilization and containment of patients onto spine boards or other devices. Adaptable to all spine boards and to all patients, thanks to the extension system on the longitudinal belt. Made with 50 mm polypropylene tape, which before sewing, undergoes a special treatment which renders it soft. The strap fixation system assures simple and quick use. Once folded and wrapped together with a practical tape, T-straps find a place in all immobilization kits.
