Kraft Box Dividers Slotted to Fit Your Box

What are slotted dividers used for?

Dividers stop items touching. That is the whole job, and it solves a surprising number of problems for small businesses.

Jam and pickle makers use them to keep jars apart in a carton. Gift shops use a shallow grid to display small items in a tray. Workshops keep screws, beads or spare parts sorted in a 24 cell grid. Bakers use a four cell divider in a lid-and-base box to keep different treats apart.

You will find them in our inserts and dividers for kraft boxes range with bottle packs and bin boxes.

How do slotted dividers fit together?

Each strip has slots cut halfway down its height. One set of strips runs lengthways with the slots facing up; the other runs across with the slots facing down. Push them together and they lock into a grid.

One of our photos shows exactly this: loose strips stood beside a box, and the same strips locked into a twelve cell grid inside it. No glue, no tape, and the grid lifts out in one piece.

1. Lay the long strips side by side with the slots pointing up.
2. Drop the short strips onto them with their slots pointing down.
3. Press down evenly until the tops line up.
4. Lower the finished grid into the box and square it against the walls.

How many cells do you need?

Count how many items go in each box, then decide on rows and columns. Six jars could be two rows of three or one long row; the box shape changes with each layout.

The starting sizes below are inside box sizes. They are a guide, not stock sizes.

How tall should a divider be?

For jars and bottles, the dividers usually come up to the shoulder or a little higher, so the glass cannot tip and touch its neighbour. They do not need to reach the very top.

For a shallow display tray, like the many-celled tray in our photos, the dividers run almost the full depth so each item sits in its own pocket.

Tell us the height of the item and the height of the box. We usually set the dividers a little below the box top so the flaps fold flat over them.

Which board are the dividers made from?

Most dividers are cut from brown kraft corrugated, which stands upright well and gives each cell a firm wall. For small, light items in a gift box, brown kraft folding board makes a thinner, neater grid.

We suggest the board when we see your items. Other corrugated grades and white-lined kraft are available on request.

Brown kraft also hides the light marks that glass leaves as it slides into a cell. A grid that has been used a few times still looks tidy.

Can you make the outer box as well?

Yes. We can make a plain or printed shipping box sized to the grid, or a lid-and-base box for a retail set. Ordering both together means the grid and box are cut to match each other.

If you already have boxes, send their inside size. We cut the dividers to fit with a little clearance so the grid drops in without forcing.

• Regular shipping cartons with top and bottom flaps
• Lid-and-base boxes for gift sets
• Shallow open trays for display
• Your existing boxes, if you send the inside size

Do dividers need printing?

Most are left plain brown. They sit inside a box and their job is practical.

Plain strips also let you reuse the same grid for different products without a mismatched design showing.

A printed grid makes sense in a gift box or a display tray, where the customer sees the cells. A simple one-colour pattern or a number in each cell works well on kraft. If you are new to printing on brown board, our guide to printing black, white and colour ink on kraft explains how inks look.

What are the common divider mistakes?

A divider order goes wrong in a few predictable ways.

• Measuring the outside of the box instead of the inside
• Cell size taken from the jar body, not its wider lid
• Ordering dividers taller than the box, so the flaps will not close
• Using one grid for two jar sizes, so the smaller jars rattle
• Forgetting room for wrapping if items are sleeved before packing

Can dividers organise a stockroom or a workbench?

Yes, and this is where the shallow grids earn their keep. A 24 cell tray on a shelf keeps buttons, findings, labels or spare fixings sorted by type, and each cell can carry a small label.

Jewellery makers and repair workshops use them as open trays on the bench. Shops use the same trays under the counter for small stock that would otherwise end up in a jumble.

If you want something that stands upright on a shelf and opens at the front, look at bin boxes instead. Divider trays suit drawers and flat shelves where you look down into the cells.

Packing with dividers day to day

Build a stack of grids before a big packing session. They lift in and out of boxes easily, and a pre-built grid saves a lot of fiddling at the bench.

Load cells from the far corner towards you so you do not reach over packed items. Close the box flaps over the top of the grid and tape as usual.

Flat strips store in very little space, so keep spares on a shelf for busy weeks.
