A4 Box Stak — frequently asked questions
What are the dimensions of the WestonBoxes A4 Box Stak and how many boxes does it hold?
The A4 Box Stak measures 345 x 325 x 235mm externally and holds five standard WestonBoxes A4 storage boxes in a vertical stack. Each box slides out individually from any position without disturbing the others.
Does the A4 Box Stak fit in an IKEA Kallax unit?
No — the A4 Box Stak does not fit inside a standard IKEA Kallax-compatible shelving unit. If Kallax compatibility is important to you, the A5 Box Stak and the Pen & Pencil Box Stak are both compatible with standard IKEA Kallax shelving units.
Can I use the A4 Box Stak frame with boxes I already own?
Yes — the A4 Box Stak is available as a frame only, making it ideal if you already own WestonBoxes A4 storage boxes. The frame is compatible with all standard WestonBoxes A4 boxes including the Crafty Tool Box, which shares the same external footprint.
What material is the WestonBoxes A4 Box Stak made from?
The Stak frame is black polypropylene — a durable, recyclable plastic. The included boxes are available in PP5 polypropylene in clear transparent, a range of transparent colours, TOUGH high-impact opaque white, or a multicolour set with one box in each of the five transparent colours: red, pink, purple, blue, and green.
Where is the WestonBoxes A4 Box Stak made?
The A4 Box Stak is designed, manufactured, and quality-checked at our factory in Sunbury-on-Thames, Surrey. S.B.Weston Ltd has been manufacturing precision injection moulded products in south west London since 1948 — originally from a factory in Teddington, then on Platts Eyot, a small island in the Thames, before moving to our own factory premises in Sunbury-on-Thames in 2002. When you buy a WestonBoxes product, it is genuinely made in Britain — not just branded here.
