The DH630 Compact In-Line Document Holder from 3M is designed to be positioned in-line between monitor and keyboard. An elastic line guide marks your place and keeps pages open. The 14" wide backplate supports books, catalogs, and just about any size document. This document holder can stand alone on a desktop or hang over the edge with the included Command Adhesive Strips. By keeping documents positioned as close to your computer monitor as possible, you can reduce eye, neck, and shoulder strain to enhance comfort.
