Stand 21 Replacement Sliding Tether
The FHR sliding tether set is FIA 8858-2010 approved and allows a greater freedom of movement in racing conditions while maintaining the safety and performance of an FHR system. The sliding tether allows head movement for unlimited side to side vision, can be retro-fitted to any FHR device ever made as it contains everything you need to convert one FHR device (tether carriers, tether, screws and full instructions included).
The sliding tethers are available in three different lengths:
The standard length for a Medium device is 450mm (18”)
The standard length for a Large device is 475mm (19”)
For users with open face helmets where the clips are located further back on the helmet or those looking for a slightly shorter version Stand 21 offer a Small 425mm (17”) length.
*Just like your racing harness, if you have had a big accident also replace your FHR tether, it has done it's job during the accident and stretched!!
