The LGU is a girder hanger designed for use with Strong-Drive® SDS Heavy-Duty Connector screws to make installation fast and easy, without predrilling. This face-mount hanger can be used for retrofit on the framing members after they are temporarily placed in position. The LGU is available skewed up to 45° or with one flange concealed.
Available in many sizes for glulam or structural composite lumber
Galvanized. Some models available in HDG; see Corrosion Information.
Use all specified fasteners; see General Notes.
Install with 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the GU series. (Note: lag screws will not achieve the same loads.)
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.
All multiple members must be fastened together to act as a single unit.
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.
Hot-dip galvanized available. Order as “X” version; specify HDG.
Other seat widths available. Order as “X” version; specify width.
