Abstract

The invention is directed to a skid plate and a method for attaching the skid plate to the bottom surface of a pre-hung door assembly to improve wear and moisture resistance. The skid plate includes a first side having a first shaped portion configured to conform to the bottom end of a first doorjamb arrangement and a second side having a second shaped portion configured to conform to the bottom end of a second doorjamb arrangement. The method for attaching the skid plate to the pre-hung door bottom surface includes applying an adhesive to bond the skid plate to the bottom surface, positioning the skid plate so that the first shaped portion and the second shaped portion align with their respective doorjamb ends, engaging tabs against the frame side surface to the doorjambs, and driving fasteners through the skid plate and tabs.
