Business Source BSN33127 1-1/2" Slanted D-Ring Binder Blue 375 Sheets

Slanted D-Ring Binder for Large Projects

This Business Source binder uses slanted D-rings that hold up to 25 percent more paper than same-size round rings. The 1-1/2 inch back-mounted rings secure up to 375 sheets while keeping pages flat. A transparent spine label holder allows quick identification on crowded shelves. It is suited for offices managing training manuals, reports or presentations.

Upgrade from Standard Round-Ring Binders

The slanted D-ring design replaces traditional round rings by increasing capacity in the same spine width. Back-mounted, no-gap rings eliminate the page curl and misalignment common with side-mounted mechanisms. Double opening and closing boosters reinforce the action so the binder stays tightly shut during transport. The jump is worthwhile when current binders overflow or pages refuse to lie flat.

Sustained Daily Use in High-Volume Filing

Under continuous handling the no-gap ring closure resists spring fatigue and keeps documents aligned without gaps. Interior utility pockets absorb loose sheets that would otherwise strain the rings during frequent access. The rigid covers and reinforced spine maintain structural integrity when the binder is stored fully loaded on its side. Heavy daily reference workflows benefit from the consistent lay-flat performance.
