Abstract
A frame for a door or window includes a plurality of frame portions, which may be lineals, and a plurality of corner blocks. For a door frame, three frame portions and two corner blocks are used. For a window frame, four frame portions and four corner portions are used. Each corner block comprises first and second mounting flange portions for attaching the corner block to a surface, such as an exterior wall of a building. First and second channel portions are each attached to a respective mounting flange portion. Each of the first and second channel portions is shaped to engage a respective one of a first and a second frame portions. A cover portion is attached to both of the first and second channel portions. The cover portion has first and second overlap portions which overlap the first and second frame portions, respectively, when the first and second channel portions engage the first and second frame portions. An ornamental "rosette" may be attached to the cover portion of the corner block.
