Sturdy report cover neatly binds and covers presentations, reports, manuscripts, proposals or other documents that require loose-leaf style binding. Two-piece cover compresses material tightly to reduce bulk. A 2-3/4" metal prong fastener with compressor holds your legal-size report tightly together without damaging the document or the binder hinge. Matching colored Tyvek hinges on the top binding give the covers a professional appearance while aiding in color-coding. Report cover expands up to 2" (250 sheets) and is made of 20 point pressboard.
