First, align the numerically marked side of each hemisphere to the inside of the opposing hemisphere's unmarked side.
Second, rotate back and forth to release any feathers.
Third, place finger pressure on the raised numbers of each half. Press to lock. Do not apply a constant, increasing force. The collar is designed to lock easily. Recheck alignment of the two halves or try shifting pressure points slightly. After locking, verify the collar turns freely.
Helpful Tip: When fitting smaller collars, place a temporary mark at each numerical site. This will help to more easily identify correct alignment while placing on small patients.
Caution: Due to the unique locking mechanism, it is helpful to instruct owners on how to remove the collar should the need arise.
