All partitions are custom made without die charges to our customers.
Partitions are sets of fiberboard or corrugated strips which are cut, slotted and assembled to form a number of cells.
The number of cells equals the arrangement: 4 x 3: 12 cells, 10 x 5: 50 cells.
The cell size is measured from the center of one slot to the center of the next slot.
The cell size for a fiberboard partition is the part size plus 1/16" (length + width)
The cell size for a corrugated partition is the part size plus 3/16" (length + width)
The cell size height typically equals the height of the part being packaged.
Air cells are end cells which do not hold product. They are usually smaller than the cell size and used primarily to form a protective cushion between the inner wall of a carton and the part being packaged.
Air cells can also be used to take up space between a cell and a stock box or a carton in current use.

Strip length equals cell size multiplied by arrangement plus air cells
The strip length is typically 1/8" less than the carton box
