This is the SnoBar/ColorBar screw-down mounting bracket used for attaching SnoBar and ColorBar to metal screw-down PBR roof panels. This will fit most rib configurations as long as there is at least a 1.5” flat mounting area and high seams measuring less than 2 inches. The face of the bracket has a slot that can accept a piece of the roofing panel. The bracket comes with a base pad with punchouts for the screw holes. The mounting bracket requires 4 screws and can accept up to 6 screws. Mounting screws and bar are not included.
