Schroth FHR Flex Twist replacement sliding tether sets for normal HANS/FHR devices. This alternative design of tether to anchor post, is an alternative design that must be used with the correct Schroth Twist anchor posts on your helmet.
It has been hailed as an easier to engage and attach design, making the coupling up of the tethers to the helmet an easier and quicker operation. The 18 inch length is the standard length supplied with most medium and large HANS/FHR devices.
Schroth also offer a 17 inch length, suited to open face helmets with posts fitted further back on the helmet shell or those wishing a slightly shorter tether. The longer 19 inch length is suited to some of those x-large HANS/FHR devices.
