The Gated Buckle provides improved stability when used with child restraints. It converts your vehicles 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 Gated Buckle is used in place of a Exactus / double T fitting and can be used either on the buckle side of the belt, or the adjacent side. Because of this, it can be fitted depending on your car restraints position.
