New in sealed box.

The Ergotron 97-783 is a dual monitor and handle kit  designed to convert a compatible single-monitor mount into a side-by-side dual-display workstation, or to expand the capacity of an existing dual-mount system. It features an integrated mechanical crossbar (bow) and a padded control handle, allowing users to shift and reposition both displays simultaneously while preventing oily fingerprints or smudges on the screens.
