3M DH340MB desktop document holder

The 3M DH340MB is a desktop document holder designed for portrait orientation. It keeps reference pages upright and visible beside a monitor so users can transcribe or compare data without looking down. Office workers, students and anyone who refers to printed material while typing will find it reduces neck movement. The unit sits directly on the desk and requires no assembly.

Portrait orientation for desk use

The holder positions documents vertically, matching the layout of most letters, forms and notes. Its stable base prevents tipping when pages are turned, and the open design lets users annotate or highlight without removing the sheet. Because it occupies only a small footprint, it fits alongside a keyboard or monitor stand without crowding the workspace. The neutral finish suits professional and home offices alike.
