Abstract
Abstract A lading strap anchor is recessed in the side wall post of a railway freight car and has a rotatable band attaching handle member which is movable out of a side wall opening to provide for attachment of strap anchors. Each anchor unit also includes an arcuate guide portion which is useful in directing straping into the attaching handle. A retaining clip may be provided to retain the handle within the side wall recess. Modified version of the invention includes a rubber biasing member which abuts the rotatable handle and provides a restoring force to move the handle into the side wall nest after straping is removed.
