- The traction modules on the cervical bands and high pull headgear help to prevent accidental dislodging of the facebow. When a pulling force exceeds (approx. 2.5–3 kg / 5.5–6.6 lbs.) the traction modules separate automatically disengaging the facebow, preventing any whip-back (e.g. of the facebow). Reassembly is easy for either patient or parent. The traction module released by the clip is simply pushed back into position. Neck bands must always be used with safety modules! - Form of delivery: Neck band with relevant safety module. - Pulling force: light to 4.5 N (450 g). - Neck pad: Denim, blue. **For further product information , please contact Chat Support**
