Abstract
The present invention entails a kit of components for constructing a cased-arched opening and also involves a method of installing the components of the kit. The kit comprises a pair of side columns with each column being generally U-shaped and designed to be inserted around a terminal edge of a wall that borders an open passageway. Further, the kit includes a curved arched assembly that is opened at the top and includes a void that permits the arched assembly to be sandwiched around a lower terminal edge portion of an upper wall section that surrounds the passageway. The respective columns are designed to fit under and support the curved arched assembly and all of the components can be nailed or otherwise secured to the structure to form a cased-arched opening.
