The OEM Cardinal ClearVue Locking Slant-D Binder CRD26352 is designed for durability and functionality. It features a unique XtraLife material that prevents sticking to cover title inserts or materials stored inside, including photos and laser prints. The binder is made from a stronger, PVC-free polyolefin cover material, making it more environmentally friendly than standard vinyl. With locking Slant-D rings, this binder holds 25 percent more letter-size material than standard round rings, accommodating up to 1,100 sheets. It also includes horizontal pockets on the inside front and back covers for loose papers, each capable of holding 40 sheets.
