A stabilizer, especially for a typical interior style baker scaffold, painters scaffold, and the like; used in homes and or buildings largely by various trades reduces the undesired movement of the scaffold. The stabilizer includes a first C-shaped coupler to secure a support bar at a first bar end and a second C-shaped coupler to support a second bar end to the scaffold. This stabilizer will adapt to the typical scaffold frame, and works to eliminate the wobble, wiggle, shake and sway from the scaffold when it is erected as a single piece or as multiple pieces stacked on top of themselves for additional height.
