Why professionals choose the WestonBoxes SRA3 box

  • Heavy duty construction: Made from a thicker grade of polypropylene than our standard range, the SRA3 box is noticeably sturdy and rigid — built to handle the demands of a busy print room or studio environment.
  • Precision fit for SRA3: Internal dimensions of 460 x 330 x 55mm are sized for a full ream of SRA3 paper (450 x 320mm) — the format used by commercial printers for full bleed A3 work. A3 paper will fit in the box but is a looser fit.
  • Archival safe: Clear acid-free polypropylene means expensive specialist papers — digital stocks, coated media, fine art papers — won't be damaged by prolonged storage.
  • Simple efficiency: Drop-on lid design gives fast, single-handed access mid print run. No clips, no latches — just lift and replace.

SRA3 storage box — frequently asked questions

What are the dimensions of the WestonBoxes SRA3 box and what does it hold?

The SRA3 storage box has internal dimensions of 460 x 330 x 55mm. It is sized to hold a full ream of SRA3 paper (450 x 320mm) — the oversized format used by commercial printers when running full bleed A3 prints. A3 paper (420 x 297mm) will also fit in the box but is a looser fit as it is smaller than SRA3.

Can I use the SRA3 box for A3 paper?

Yes, A3 paper will fit in the SRA3 box, but it will not be a close fit — A3 (420 x 297mm) is smaller than SRA3 (450 x 320mm) so there will be some movement inside the box. If you are storing A3 paper and a precise fit is important, this is worth bearing in mind. For SRA3 paper the fit is precise and the paper sits flat with minimal movement.

Is the WestonBoxes SRA3 box acid-free?

Yes. The SRA3 box is made from acid-free polypropylene, which means it will not react with or damage paper, artwork, or photographic materials stored inside it. It is safe for long-term storage of expensive specialist papers and fine art prints.

What material is the WestonBoxes SRA3 box made from?

The SRA3 box is made from a thicker grade of clear polypropylene than our standard range, giving it a noticeably sturdy, rigid feel. It is not the same as our TOUGH high-impact grade, but it is robust enough for light industrial use including commercial print rooms and studio environments. Acid-free and recyclable.

Where is the WestonBoxes SRA3 box made?

The SRA3 storage box is designed, manufactured, and quality-checked at our factory in Sunbury-on-Thames, Surrey.
