Abstract: A method of preventing disruption of a taped finished drywall board joint in a room having a center ridge member and angularly inclined ceiling rafters which involves a metallic connector positioned between the wallboard sections and the ridge member and rafters. The connector has two metallic wings with a center longitudinal bendable connection. The wings have flexible tabs at their free edges which are attached to the rafters and the connector itself is attached to the wallboard adjacent to the ridge member. The wallboard also is attached to the rafters 8-12 inches from the edges of the wings. Because the tabs can bend away from the wings, this construction allows the joint to flex if the rafters warp or shrink without disrupting the finish coating on the outside of the wallboard joint at the ridge member. The connector also can be applied to other critical joints in a home where the framing members are subject to movement such as flat ceilings to avoid truss uplift or rafter movement.

Abstract: A boxable corner bead for finishing drywall corners that is made from two flanges with a protruding nose section. This bead can be made in regular, bullnose, or flex trim type arrangements. Once the bead is attached to a drywall corner, it can be mudded on both sides of the corner without waiting for the mud on the first side to dry. This is because of the shape of the nose which allows a mud dispensing box to apply mud on one side without getting mud on the nose. The box can then be immediately moved to the other side, where that side can be mudded. The nose itself is prepared to directly receive paint or texture, and hence does not need any mud. A version of the device has a raised trapezoidal, triangular or bull-nose section with a V-groove cut in the back. The bead hinges around the V-groove to match any corner angle. Both sides can be mudded as with the fixed bead. The beads can be used with both interior and exterior corners.
