STAND 21 ULTIMATE ULTRA-LIGHT FRONTAL HEAD RESTRAINT (FHR)
Stand 21 Ultimate FHR collar in the 20° recline. With over two years of development and ten years of expertise in Frontal Head Restraint design and engineering, Stand 21 now offers the world's most evolved version to date. Weighing a mere 560 grams, the Ultimate is nearly 100 grams lighter than the other top-level devices on the market.
The all-carbon bodies of these new models combine an exclusive resin-transfer technology (RTM process) with a UD monolithic section. This refined monolithic technology allows a new design for the unit's arms with thickness greatly reduced to 4mm compared with 14mm for others' models. This allows for an optimized footprint, improving the fit between driver and harness.
The arched top has been re-engineered and redesigned completely, offering a reduction in thickness to below 2mm, increasing helmet-to-seat clearance to improve safety. The new Ultimate range includes Medium and Large sizes in 20° recline (the most popular, for use in Saloon, GT and Rally applications) and 30° recline (typically used in Single Seaters and Prototype applications with moderately reclined seats).
Stand 21 FHR collars are supplied with black padding and a protective bag for storage. All Stand 21 FHR devices come with vision sliding tethers as standard.
