Abstract
Abstract Plastic covering protects the normally exposed inner surface of a door frame from the weather and provides a decorative coating therefor which never needs painting. An additional plastic covering in the form of an elongated plastic extrusion member is attached to the back side of the door frame adjacent the exterior wall and has a rigid plastic strip or fin projecting therefrom covering the joint between the door frame and exterior wood sheeting to provide a drip cap along the top of the door frame and water seal around the entire periphery of the door frame. The plastic fin is offset with respect to its base portion to accommodate the difference in thickness between dry wall and plaster wall for use with either by proper positioning of the fin.
