Car seat belts can sometimes be too tight at the shoulders, neck and face. The Seat Belt Tension Adjuster easily clips onto the shoulder belt to provide additional slack for driving comfort.

Then simply slide the red tab to the locking position to secure the seat belt clip in place. Designed to accommodate all standard seat belt widths, the two Adjusters in this pack are great for use in your vehicle, rental car, charter bus and more! The compact size makes them portable, so have one on hand wherever you go! Made from sturdy plastic, the Adjuster will last through regular and normal usage once correctly secured in place. The design of these seat belt adjuster clips ensures comfortable handling and unparalleled convenience. These make great gifts and you can have extras in every car. Keep them in your bag, purse or backpack. Contents: 4 pieces
