Cardinal CRD26331 3 Inch Black D-ring Binder Locking Slant-d

Product Description

The CARDINAL CRD26331 is a 3-inch capacity D-ring binder built for heavy-duty document organization in office and professional environments. The cover is constructed from XtraLife polyolefin, a durable material that resists sticking to inserts, photos, and printed sheets. A chipboard core adds rigidity to prevent flex and distortion under load. Locking Slant-D rings provide a secure closure and hold approximately 25% more letter-size sheets than standard round rings of the same nominal size. Cold-crack testing to -50 degrees F confirms the cover material stays flexible and intact in extreme cold storage conditions.

This binder is suited for letter-size document filing in office, school, and professional settings. It is a standard 3-inch capacity unit appropriate for high-volume filing projects, long-term archival storage, or any application where binder durability and ring integrity are critical. The nonstick clear overlay on the cover accepts custom inserts for labeling and identification. Horizontal pockets inside both the front and back covers each hold up to 40 loose sheets, providing additional storage without added bulk. Exposed rivets at the spine reinforce the hinge connection.

Installation Notes

Do not overfill beyond the rated sheet capacity, as exceeding capacity can stress the ring mechanism and reduce service life.
