Who It's For:

Essential for professionals who frequently reference paper documents while working on a computer — including data entry specialists, transcriptionists, accountants, administrative assistants, legal professionals, and anyone who types from hard copy materials. Perfect for reducing neck strain during document-intensive tasks.

Expert-Recommended Ergonomics:

Ask Ergo Works has been helping organizations create healthier workspaces for over 30 years. The 3M In-Line Document Holder is a cornerstone of our ergonomic assessments for document-intensive work — proven to reduce neck rotation, prevent forward head posture, and eliminate the repetitive strain caused by constantly looking down at papers on your desk.

The Science of Document Positioning:

Ergonomic research shows that repeatedly turning your head to view documents placed to the side of your monitor creates cumulative strain on neck muscles and cervical spine. Similarly, looking down at papers on your desk forces harmful forward head posture. The in-line design positions documents at eye level in your central viewing zone, maintaining neutral neck alignment and reducing musculoskeletal stress.

Boost Productivity & Accuracy:

Beyond comfort, proper document positioning improves work efficiency. When reference materials are at eye level and in-line with your monitor, you'll experience fewer transcription errors, faster data entry, and reduced eye fatigue from constant refocusing between different viewing distances and angles.

Transform your document workflow today — and experience the difference that expert-designed ergonomic document positioning makes. Your neck, shoulders, and productivity will thank you.
