Universal spider straps system for spine board allows complete immobilization of adult or paediatric patients onto Spencer spine boards but also onto other types of spine boards. Thanks to the diagonal parts, which move on the central belt, it adapts itself with precision to different body builds. Fixation is with self-adherent strips. To simplify use, the straps are colour-coded. Completely X-ray compatible. They are made of strong but soft 50 mm nylon tape and are sewn together with special lockstitching techniques.
