The Fas-Trac� Ratchet Suspension system, which contains no metal parts, is an easily adjustable, snug-fitting system specialy designed to work with MSA Protective Hats and Caps to provide essential crown clearance to absorb impact energy.

Do not mix MSA and non-MSA suspensions and helmets (example: MSA helmet with non-MSA suspension).
FAILURE TO COMPLY WITH THE ABOVE WILL REDUCE THE ENERGY ABSORBING ABILITY OF THE PROTECTIVE HELMET WHICH CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
