发明名称 Metal door frame and trim clip
摘要 A metal door frame has trim molding applied to its flanges by the aid of separate clips. Each clip interfits an aperture in the flange and a notch at the flange edge. The aperture and the notch are punched in the flange so that the spacing thereof from the corner of the flange is constant whereby alignment of the clips is assured notwithstanding lack of critical dimensional control of the flange.
