The Britax ClickTight Anti-Rebound Bar accessory easily attaches to any Britax ClickTight convertible car seat when used rear-facing, offering additional protection for your child. The ClickTight Anti-Rebound Bar rests against the vehicle seat back, protecting your child's head from injury by reducing the amount of rearward movement in the event of a rear or frontal collision. Made of strong steel and covered by soft, padded fabric, the ClickTight Anti-Rebound Bar is just one example of how Britax develops innovative products to help ensure your child's safety and comfort.
