Does your seat belt rattle and slap? This is most noticeable on the passenger side when you don't have a 'co-pilot', or when you are on track and wearing harnesses instead of the 3-point belt. Put an end to that annoying rattle with our self-adhesive seat belt retainers. Installation is a breeze. Just clean the area with the included swabs, peel off the adhesive backing, and press the holder firmly in place for a few seconds.
