These bins replace the rectangular bin in the low profile packout organizers (48-22-8431 and 48-22-8436).  They come in a variety of configurations and custom configurations or colors are available upon request.  While these can replace 2 of the stock square bins, you might want a taller middle divider that follows the contours of the lid to help keep parts in place (see photo of 12-way bin, as an example).
