Bantex A3 Upright Ring Binder 4D 38mm Black Box of 8

This binder is built specifically for A3 upright documents. The internal dimensions - 360mm length by 445mm height - accommodate standard A3 sheets filed with the long edge vertical, which is the correct orientation for technical drawings, plans, and oversized prints.

A 38mm ring capacity generally holds approximately 380 sheets of standard 80gsm paper. Actual capacity may vary slightly depending on paper weight and thickness. The 4D ring profile helps pages lie flat, which makes the most of the available ring space.

A 4D ring mechanism uses four D-shaped rings positioned so the flat back of each ring aligns perfectly when closed. This keeps pages flat across the full depth of the binder rather than fanning at the spine, which reduces wear on punched holes and makes the binder easier to use and read.

This listing is for a full box of 8 Bantex A3 Upright Ring Binders. The price shown is for the complete box. If you need a smaller quantity, please contact our team to check availability of individual units.

Yes. The reinforced lower edge helps the binder withstand repeated shelving and retrieval without breaking down at the base. The lower spine label pocket supports clear long-term labelling. For archiving documents that need to be retained for many years, pair these binders with archival-quality sleeves or pockets.

You will need an A3-capable 4-hole punch to prepare documents for this binder. Standard A4 punches are not compatible with A3 upright filing. Bantex and other suppliers offer A3 punches that match the ring spacing used in these binders.
