The center line position of the anchors should be 1.5" from the base of the helmet, and 6" forward from the center of the rear of the helmet. (use a stagger tape so it can easily bend around the surface of the helmet. That rear centerline point should also be 1.5" from the base of the rear of the helmet.
Some helmets have molded features that require you to adjust these positions, so you are on a smooth surface. Usually no more than a quarter or half in. adjustment is needed. I always try to use that 1.5" line as a minumum though and adjust up if needed.
For complete instructions go to:
www.hansdevice.com then click Resouces link and "Anchor Install Instructions"
to see a pdf. of illustrated directions.
Not sure why your anchors are not the same on your helmets?????Should be if models are the same. pm me on that one.
