Briggs & Riley publishes two dimension sets for each wheeled bag: Exterior Dimensions (includes wheels & handles) and Case Dimensions (excludes wheels & handles). The exterior set is the overall gate sizer measurement and is stored in exterior; the case set is stored in bodyOnly. Depths are listed as a compressed to expanded range, so the stored exterior depth is the compressed value and expandedDepthIn is the expanded value. All dimensions are published in inches with cm secondary.
