Quick release helmet hardware set for DefNder G70 and Team Issue. Includes backing plate for older helmets. If you are installing into an SAH2010 or SA2015 helmet that has pre-bonded and threaded inserts, we recommend using an 1/8″ thick rubber washer between the quick release and your helmet shell. This will allow you to adequately tighten the hardware and clock it in the correct direction. Otherwise it may end up tight, but facing the wrong way.
