Double-wide polypropylene panoramic sheet protectors allow you to customize presentations over a 17" wide spread. Sealed on three sides like top loading holders, but documents are inserted from the center. The fold-out feature allows the holder to be stored in standard, letter-size binders, while being able to display one 11" x 17" page (often called Tabloid, Ledger or ANSI B size) or two 8.5" x 11" size documents. Once the documents are in place, simply fold the sheet protector along the center to put it back in its original position. Acid-free material eliminates photocopy transfer. Pre-punched to fit standard three-ring binders help keep documents in their original state. This product will be cheerfully replaced with one of equal value if defective in materials, manufacturing or packaging at the time of purchase. Except for such replacement, this product is sold without warranty or liability even though defect, damage or loss is caused by negligence or other fault. Load Orientation: Center; Sheet Capacity: Four 8.5 x 11 or Two 11 x 17; Sheet Protector Type: Ring Binder; Insert Size: Two 8.5 x 11; One 11 x 17.
