Laedral Medical Stifneck® 260203 Adult No-Neck Extrication Collar. The original Stifneck® with outstanding motion restriction and optimal sizing. Others may look like the Stifneck® collar, but there's only one original. Due to color coded collars and an accurate finger sizing method, sizing collars to patients is easy. The collars provide outstanding motion restriction without hyperextension or limiting access to airway, and an oversized tracheal hole enables pulse checks and advanced airway procedures. To prevent the worsening of a potential spinal injury, it is vital that the extrication collar is sized correctly.
