These clever stabilising clips from Stand 21 are designed to keep your shoulder straps secured in place on your HANS device. The clips slide over the yoke of your FHR to provide additional security for your harnesses while competing. These fixings, known as "equerres" in France - where Stand 21 products are made - do a fantastic job of keeping everything in line. These very lightweight clips only work with Club Series 3, Ultimate and Featherlite devices and are supplied as a pair. For ultimate performance these should be used with HANS type harnesses with 2" (50mm) shoulder straps.  As used in Formula One by leading drivers who wear Stand 21.
