Abstract

A mounting bracket (220) for a trapezoidal rib (204) is disclosed. The mounting bracket (220) includes an upper wall (224) in the form of a flat surface for supporting various types of attachments. An attachment may be secured relative to the mounting bracket (220) using a mounting hole (226) on the bracket upper wall (224). The bracket upper wall (224) is disposed above the trapezoidal rib (204) by a pair of rib offsetting members (246a/b) that are disposed within a hollow interior (248) of the mounting bracket (220), and that are seated on the upper wall (206) of the trapezoidal rib (204). A threaded fastener (114), engaged with the mounting hole (226) on the bracket upper wall (224) to secure an attachment relative to the mounting bracket (220), terminates within the hollow interior (248) of the mounting bracket (220).
