When ordering multiple units of the The ColumnStore™ column storage boxes are shipped with labels placed on each ColumnStore 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 must use a mounting bracket (special order item) to join two units together. The top box does not have a mounting bracket.
If you order the units at different times, simply order the mounting bracket shown below and stack the units placing the bracket between the storage units.
