Bantex A3 Insert Binder 4D Ring 38mm White Box of 8

The ring capacity is 38mm. Based on standard 80gsm paper, a 38mm ring typically holds approximately 380 sheets, though actual capacity varies depending on paper weight and any use of dividers or plastic pockets.

A 4D ring mechanism uses four D-shaped rings positioned so that pages lie flat and aligned when the binder is open. This reduces the page curl and off-centre lifting common with round-ring binders, making it much easier to read and work with large A3 documents.

The binder has a clear plastic overlay on the front cover, back cover and spine. You simply slide a printed or handwritten sheet behind the overlay to label and personalise the binder. No printing directly onto the cover is required, and the insert can be swapped out if the binder is repurposed.

This listing is for a full box of 8 binders. Buying by the box reduces the per-unit cost and is ideal for studios, schools or offices that need a consistent supply of matching A3 binders across multiple projects.

Yes. The A3 format and 4D ring mechanism make these binders well suited to technical drawings, blueprints and engineering documents. The flat-opening ring design keeps sheets accessible and readable without bending or curling the document edges.

Each binder measures 355mm in length, 445mm in height and 55mm in width, with a weight of approximately 0.8kg. These dimensions are for the binder itself and should be considered when planning shelf or drawer storage for A3 filing.
