This radius chair rails sheetrock bullnose corner is made of solid poplar for painting or staining. Actual size is about 2″ tall and 1″ deep.
We make our radius corner chair rail mouldings with integrated tangent straight legs. That means each moulding goes at least 3/4″ down the straight wall on either side of the rounded corner. The result is an easier installation process and a larger corner moulding. Radius corners that only cover the 90 degree curve tend to loosen over time and make the joint more visible.
