The Exactus Locking Clip provides improved stability when used with child restraints. It’s an innovative way to convert the vehicle lap & sash belt into a lap only belt. This can be useful when installing a child restraint and can result in a tighter fit. The Exactus is used in place of a gated buckle / double T fitting. Additionally, it can be used either on the buckle side of the belt, or the adjacent side. Because of this, it’s much easier to fit depending on your car seat position.
