Because this solid rubber ramp features a flat, vertical 90-degree back wall designed to sit flush against a perpendicular vertical step, it will not sit flush or be stable if your doorway has an outward-sloping bevel or angle without leaving an unsupported gap. Also, for further assitance please check first whether your floor dimensions match with the product dimensions or not.
