Quarter round
Quarter round is a convex molding with a cross section in the form of a quarter circle.
A variation is a base shoe, a quarter of an ellipse.
Most quarter round is of small gauge and relatively flexible. It is typically used as a decorative build-up element in mantels and other architectural features, and at the lower edge of baseboard to hide any gaps between it and a floor. Base shoe is used similarly in flooring applications.
Quarter round is produced in hardwood, softwood, engineered wood, and extruded plastic.
