1-1/2" Capacity D-Ring Binder

The Business Source 28447 binder uses Slant D-rings to hold up to 375 sheets, offering 25 percent more capacity than traditional round-ring models. A clear overlay on the front, spine and back cover allows quick customisation for easy identification. Two trigger mechanisms provide smooth opening and closing for frequent access. It suits office workers and students who need a high-capacity, customisable filing solution.

Thermals noise power

Not applicable. This binder is a passive office supply with no electrical components, cooling requirements or noise output. It draws zero power and produces no heat during normal use. The polypropylene cover and chipboard core are PVC-free and transfer-safe, so documents remain protected without any environmental controls.

375-sheet Slant D-ring capacity

The single specification that decides fit is the 1-1/2 inch Slant D-ring capacity rated for 375 sheets. Buyers who need to store larger volumes should look for a binder with a greater ring size. Users who prefer standard round rings or require a smaller footprint for limited shelf space will find this model unsuitable. Each inside pocket adds 30-sheet supplementary storage.

Questions about this item

How do I insert the first sheets so the 1-1/2" Slant D-rings align correctly?

Open both triggers, lay the punched pages onto the back-mounted rings, then close the triggers firmly; the slant design lets the 375-sheet capacity lie flat without forcing the cover.

What part of the 28447 binder wears out first and needs replacing?

The two metal ring triggers take the most repeated stress; if a trigger spring weakens, the rings will not stay closed and the mechanism should be swapped.

At what fill level do the inside pockets stop accepting extra pages?

Each clear pocket holds 30 sheets; once you exceed that the pocket lip buckles and pages slide out when the binder is carried.
