Hans Device Anchors
There are currently 2 types of anchors to connect your Hans Device to your racing helmet.
The Hans Post Anchor is the most common system. The HANS is attached to the helmet by aligning the tether hardware to the helmet hardware, pushing in and sliding the tether rearward. To release, realign slots on tether hardware to flats on helmet hardware and slide forward.
The Hans Quick Click system is quickly gaining popularity by allowing the driver to quickly detach the head and neck restraint from the helmet by pulling on the orange tethers. To attach the HANS to the helmet anchors, open anchor by pulling orange release strap, slide tether loop over the hasp and close.
