LGU/MGU/HGU/HHGU High-Capacity Girder Hangers

LGU/MGU/HGU/HHGU

Face-Mount Hangers for Structural Composite Lumber

This product's information may differ depending on the category of use. You are currently viewing details related to Face-Mount Hangers for Structural Composite Lumber. You can also view product information related to the category: Face-Mount Hangers for Glulam Beams

The GU hangers are high-capacity girder hangers designed for situations where the header and joist are flush at the top. These products can be used for retrofit on the framing members after they are temporarily placed in position. Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws (included) make installation fast and easy, with no predrilling required.

Material

  • See table

Finish

  • Galvanized; HHGU — Simpson Strong-Tie® gray paint. Available in hot-dip galvanized; order as “X” version and specify HDG.

Installation

  • 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 GUs. (Note: lag screws will not achieve the same loads.)
  • Alternatively, the Strong-Drive SDS 1/4" x 2 1/2" face screws supplied with these hangers may be replaced with SDS 1/4" x 3 1/2" or SDS 1/4" x 5" screws for 2-ply or 3-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.
  • For installation to concrete or masonry walls, see LGUM and HGUM hangers.

Options

  • See Hanger Options General Notes.
  • Hot-dip galvanized available. Order as “X” version; specify HDG.
  • Other seat widths available. Order as “X” version; specify width.
