A two-piece anchor assembly has a retainer and an interlocking link. The link is a unitary component that is formed by a single forging step. The link is secured to the floor of a railway flatcar by the retainer. A steel band is connected at one end to a load bearing surface of the link of a first anchor assembly and at another end to a load bearing surface of the link of a second anchor assembly. A tensile force is then applied to the steel banding and crimped with a clip in order to secure cargo. The load bearing surface has an enhanced banding radius, which reduces the risk of band breakage when the steel band is subjected to a high tensile force by preventing “creasing” at contact locations.
