As extruded from a polymeric material, such as polyvinyl chloride, a drywall-trimming strip has a central portion, which has a bullnose region and two planar regions, one at each side of the bullnose portion. Further, the drywall- trimming strip has two lateral flanges, each of which is joined unitarily to the bullnose portion by a stepped junction. The bullnose region has an exterior radius of 0.350 inch approximately. Each planar region has a width of 0.217 inch approximately, as measured in a plane normal to an axis defined by the bullnose region. Each junction has a measurement of 0.095 approximately, as measured between a plane defined by the exterior surface of the bullnose portion and a plane defined by the interior surface of the flange at such junction. Having a thickness of 0.055 inch approximately, the strip is adapted to fit along an elongate corner defined by two drywall panels, each of which has a thickness not less than 0.5 inch approximately and each of which is disposed against an interior surface of one of the lateral flanges, while permitting a first panel to abut or to be closely spaced from a second panel without requiring the second of panel to be set back from a plane defined by an outer surface of the first panel, by a distance larger then 0.091 inch approximately, so as to avoid interference with the bullnose portion.
