Safely display your collection's documents with this Acrylic Document Mount with Museum Board Support. Part of the Xibitmount™ Document Display System, each mount is constructed of 1/8" acrylic with polished edges and available in a wide range of sizes. 4-ply Alpharag museum board is mounted flush to the surface of the acrylic mount to provide additional support. An integrated 1/4" acrylic cleat on the back of the acrylic document mount corresponds to an adjustable cleat on the acrylic stand (sold separately). With interchangeable acrylic document mounts, institutions can easily rotate documents for display.
