Arch jamb leg interface

Abstract

There is provided an arch assembly comprising a pair of opposing vertical jamb members each including internal and external surfaces and a top surface at distal ends thereof. The external surfaces thereof preferably abut opposing parallel sides of a door frame. An arch jamb is interposed between the vertical jamb members. The arch jamb defines a curvature, opposing connective ends, and an upper surface. The connective ends each include a leg interface defining first and second vertical faces, and a horizontal face interposed therebetween. The first vertical face is configured to mate with the interior surface of the respective vertical jamb member. The horizontal face is configured to mate with the top surface of the respective vertical jamb member. The second vertical face is configured to engage the respective opposing parallel side of the door frame. The engagement of the leg interface provides structural stability of the arch jamb.
