A drywall trimming element for bridging two sections of drywall is an extruded element having first and second opposing flanges each having an interior surface and an exterior surface. The element is secured to the drywall by joint compound. The interior surfaces are adapted to be positioned on or adjacent to a respective one of the drywall surfaces. The interior and exterior surfaces each define respective surface planes. One or both of the interior and exterior surfaces have a plurality of upstanding longitudinally oriented ribs extending outwardly from the surface. The ribs extend away from their respective surfaces and define a void space between the surface adjacent to the ribs and an end of the ribs, such that a line extending outwardly from and normal to the surface of the flange adjacent to the ribs traverses through the void space and then subsequently contacts the ribs. The void space serves to provide a joint compound locking feature for the trimming element. |
