The ColumnStore™ column storage boxes are designed and shipped with labels placed on each unit which read “Box 1 of 3″/ “Box 2 of 3″/ “Box 3 of 3” for example. This will indicate the order that the boxes should be stacked. Follow the instructions in the below to stack the boxes. You use a mounting bracket to join two units together. The top box does not have a mounting bracket.
