Abstract: Apparatus for the restraint of cargo in carriers such as freight containers, highway trucks and trailers, railroad cars, ships, aircraft and space vehicles. The apparatus includes continuous rails which are fastened flush to the floor of the cargo carrier and to the structural supports of said floor. A continuous undercut groove in the rail serves to fasten, at any point, load restraint chocks which are braced directly against the cargo loads. The chocks are designed with eyes and other tie-down anchor means to which flexible straps about the cargo load are anchored. The chock may also be fabricated with an adjustable blocking member to fit against a lateral side of a cargo load so as to apply additional lateral bracing to the cargo load.
