Bantex A4 Insert Binder 4D Ring 38mm Black Box of 15

The ring capacity is 38mm, which typically holds around 350 sheets of standard 80gsm A4 paper. This makes it well suited to medium-volume project files, reports and training materials. For higher volumes, Bantex offers binders with larger ring sizes.

A 4D ring mechanism uses four rings in a D-shaped configuration that closes flush, rather than the traditional O-ring. This keeps pages lying flat when the binder is open, reducing page curl and making it easier to read and write on documents. It also allows more sheets to fit within the stated capacity.

The binder has a clear overlay pocket on the front cover, back cover and spine. You simply print your own cover page and slide it in behind the clear panel. There is no adhesive or laminating required, so updating covers between projects takes seconds.

This listing is for a full box of 15 binders. The price shown reflects the box quantity, making it an efficient bulk purchase for teams, offices or school administrators who need consistent filing across multiple users.

The standard PP (polypropylene) cover is moisture-resistant and durable enough for everyday office handling - desk use, meeting rooms and storage. It is not rated for industrial or outdoor environments. For heavier-duty requirements, consider a rigid board or heavy-duty PP binder.

This model uses a standard PP cover, which is lightweight and flexible - ideal for regular office filing. Heavy-duty Bantex binders typically feature a thicker board or reinforced spine for applications where binders are handled more frequently or stored under pressure in packed shelving.
