These FIA and SFI Certified Camlock harnesses from Proforce are constructed from premium nylon webbing and a high-quality cam buckle. Funnel-style receivers in the Camlock make plugging in the belts a snap! They feature an ultra-lightweight magnesium case and a high-tech, quarter-turn mechanism. Each belt will rotate up to 40° and move up and down 10° to conform to the driver's body. This provides an extra measure of comfort compared to other camlock buckles.
