Chief Over-the-Whiteboard Interactive Display Mount (OB1U)

Heavy-Duty Mounting Over Existing Chalkboards / Whiteboards

The Chief OB1U makes it simple to install large interactive flat panel displays over existing whiteboards or chalkboards — without demolition or surface removal. Arriving largely pre-assembled, it minimizes install time and allows adjustable placement for accessibility — ideal for classrooms, front-of-room corporate training, and ADA-conscious environments.

Supports large displays 50–80" with up to 310 lb (140.6 kg) capacity.

This rail-based system anchors into multiple wall types and offers telescoping legs for flexibility around existing obstructions, conduit runs, or cabinetry.
