Installation
NOTES
The yoke-style retention assembly contains two holes (eyelets) in each strap. The recommended
installation procedure is to use the lower strap holes in the size regular helmet and the upper strap
holes in the size x-large helmet. However, if the helmet does not fit properly with the retention
installed in this manner, the settings may be changed as required.
The front retention straps on each side raise and lower the earcups.
The rear retention straps control the forward and aft earcup positioning.
The rear hanger tab adjusts the nape pad. This tab may be trimmed to prevent chafing on the neck.
