Stacker Block & Spacer

Need an extra stacker or 2 to build a box?

Look no further!

Each block is 21mm in height and you always need an odd number of Stackers on each side to make up a box frame. The minimum required number of blocks is 3 on each side to make up a 63mm (2.5") tall frame.

The most efficient way of purchasing these blocks is as a pack which you can find here: https://mattestlea.com/products/stackers

Use this product to top up what you've got or to help make irregular shapes (although they will be coming as packs in the near future too).

How do they work?

1. Slot the Stacker Blocks (the one with the hole running through it) onto the frame clamp rods before the frames are built.
2. Put together all the frames in their entirety (but don't stack them yet), roughly to the size of the box you'll be making.
3. Attach the magnetic Stacker Spacers to the Stacker Blocks.
4. Place your next frame with the Stacker Blocks already applied on top of those Stacker Spacers.
5. Repeat until complete.
