Impact's exclusive t7 webbing was designed specifically for motorsports. The laterally ribbed webbing works with Impact's patented adjuster, like a ratchet, to help prevent webbing creep. All webbing ends are wrap around or bolt in with all hardware supplied. Impact's ''lost motion'' Rotary Cam System requires rotation past a preset No Release Zone to disengage links. This feature combines with the no-snag face plate design to prevent inadvertent disengagement.
