A railcar load securement apparatus uses an array of load securement anchors having bases adapted for strength and efficiency in mounting in a rail car, a plurality of vertical support members extending upwardly from a mounting base or bracket with a flush mounted anchor plate joining them, so that a plurality of tensioning members or straps can be readily mounted to retain cargo, but the anchor is flush to be unobstructive when unused. Flexibility in load adaptation is provided for in that a number of different load capture arrangements can be utilized.
