The Universal Cervical Collar is a fully adjustable collar that provides protection and support for the wearer. This collar is for both emergency and long term use, making it appropriate for whiplash. What makes this collar so effective is that it immobilizes the motion of the neck in three directions (up, down, and side-to-side). The adjustment knob in the back of the collar conforms to any size neck with ease. The outer shell is made of firm polyethylene and the inner collar is made of a soft foam. This collar is universally sized, making it suitable for any adult neck.
