The bracket of the present invention allows relative vertical movement between perpendicular building components. The bracket includes a first connector plate joined at an edge and aligned with a second connector plate in substantially a right angle to form a right angled juncture. A number of substantially triangular stiffener channels are disposed in the right angled juncture each having a substantially U-shaped cross section. A number of substantially linear stiffener channels are provided in the first connector plate that each extend from a corresponding triangular stiffener channel. The second plate includes a number of elongated slots through which the plate may be connected, with a shoulder screw or the like, to a building component. The slots allow for vertical movement of the building structure without transferring compressive loads to the building component connected to the second plate, such as an exterior curtain wall. The first plate may be connected to structural framing of the building. When the structural framing of the building flexes downward, the bracket of the present invention allows for relative vertical movement relieving stresses and eliminating and resisting horizontal forces caused by wind or seismic loads.
