The GU hangers are high-capacity girder hangers designed for situations where the header and joist are flush at the top. This part can be used for retrofit on the framing members after they are temporarily placed in position. It uses Strong-Drive® SDS Heavy-Duty Connector screws to make installation fast and easy, with no predrilling required.
Alternatively, the 1/4" x 2 1/2" Strong-Drive SDS face screws supplied with these hangers may be replaced with 1/4" x 3 1/2" SDS or 1/4" x 5" SDS screws for two-ply or three-ply LVL headers to transfer the hanger load to all plies. This alternate fastener option does not eliminate the need for uniform fastener requirements along the length of the multi-ply header.
Multiple member headers may require additional fasteners at the hanger locations. The quantity and location of the additional fasteners must be determined by the Designer.
