Abstract
A kit includes a series of components, capable of being flat packed, that can be assembled to form an arch or a section of an arch for use in a building such as a residential structure. The kit includes a pair of curved sides with each curved side including an inner face, an outer face, an upper edge and a lower edge. Formed along the inner face of each side is a curved groove. A flexible or pliable jamb is provided in the kit. Secured in spaced apart relationship along one side of the jamb is a series of clips. When assembled, the arch or arch section includes the clips extending between these sides and including portions that project into the curved grooves. The clips effectively secures the jamb to the sides.
