Profi II - 6 The Schroth Profi II 6PT Flexi Belt system is the lightest and strongest Cam Lock system available today. Features 3" polyester webbing at the shoulders and 2" polyester webbing "Flexi Design" at the lap belts, lightweight adjusters, and RFR rotary buckle. The 2" lap belt's notable feature is that it rides within the crest of the human pelvis where a 3" belt would rest on the edges. This allows you to get the belt up to an inch and a half tighter. That means the lap belt will be working earlier in the accident event because it gets loaded faster. It's also more comfortable and easier to adjust becuase there's less friction through the adjuster. The Flexi Lap belts allows both pull-up or pull-down adjustment with a simple exchange of the mounting hardware and the cam snap-in hardware from end to end. Dual substrap is clip-in. Shoulders come in 70" length. SFI 16.1 and FIA approved. Available in red, blue, and black.
