Already own WestonBoxes A5 boxes? Add a Stak frame. Frame only — no boxes included: The A5 Box Stak frame is sold separately for customers who already own WestonBoxes A5 storage boxes and want to organise them into a vertical slide-access stack without buying a complete set. Holds five A5 boxes: The black polypropylene frame holds five standard WestonBoxes A5 storage boxes in a vertical stack with individual slide-out access to any box from any position — no lifting, no shuffling, no unpacking the whole stack to reach the one at the bottom. Includes Stak brace and five box handles: The strengthening brace keeps the frame rigid under load. The five box handles clip to the front of each A5 box making it easy to pull individual boxes smoothly out of the frame.

An A5 Box Stak and a Pen & Pencil Box Stak also fit side by side inside a single Kallax cube — see our Kallax Compatible Storage Pack for the complete combination.
