door casing capital

A door casing capital is the polyurethane head piece used at the upper corners of a door casing or at the top of a side jamb to mark where the casing ends. It usually takes the form of a console, rosette or profiled crown and completes the upper transition of the door frame. It is used on interior and exterior door casings to create a classical or neoclassical look. The polyurethane material is light and applies directly with assembly adhesive; it resists moisture and impact, does not crack or swell and can be painted. Being lighter than plaster makes corner installation easier, and unlike wood it is unaffected by moisture. Because it is mould-cast, the capital details repeat identically on every piece. Polure produces door casing capitals in sizes suited to different casing widths.
