The OEM Cardinal ClearVue Locking Slant-D Binder CRD26310 is designed for durability and functionality. It features a unique XtraLife material that prevents sticking to cover title inserts and stored materials, including photos and laser prints. This binder is made from a stronger PVC-free polyolefin cover material, which is more environmentally friendly than standard vinyl. With a 1-1/2 inch ring capacity, it can hold up to 375 sheets and includes horizontal pockets on the inside covers for additional storage. Locking Slant-D rings provide a secure hold while GelTab triggers ensure comfortable operation.
