A bracket for connecting a first extruded member having spaced and generally parallel extrusion fins to a second member. The bracket comprising a base plate, a longitudinal wedge element configured to be inserted in between the extrusion fins, an extrusion fin receiving channel to receive a first extrusion fin of the first extruded member, fastener receiving apertures through the base plate to receive a fastener to rigidly couple the bracket to the first extruded member, and a deformation cavity adjacent the fastener receiving aperture configured to receive a deformed extrusion portion of the first extrusion fin. The fastener receiving aperture is located on the base plate such that the deformed extrusion portion is forced into the deformation cavity and at least partially out of the extrusion fin receiving channel to form a rigid connection in a deformed condition when a fastener is located in the fastener receiving aperture.
