Abstract
A frame is formed of side walls that are extruded from vinyl. The side walls have interior channels. The side walls may be formed to effect a female-male connection between the ends of two adjoining side walls. Alternatively a locking member is provided that is sized to frictionally engage a selected channel. The side walls have a concrete retention fin positioned to extend away from the outer wall of the side wall to interconnect with the concrete as the and after the concrete cures. The frame may be formed into door jambs, doors, and the like. The frame may also be a window buck that may be formed into selected geometric shapes. Window bucks of different dimensions may be assembled on site by sawing.
