Simpson THGB truss girder hangers are high capacity, welded hangers designed for multi-ply girder trusses. The THGB series offers optional installation with Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws, and the bolted THGBH hangers offer higher design loads. For a lower cost alternative that uses Strong-Drive SDS Heavy-Duty Connector screws instead of bolts and offers high load capacities, see the THGQ/THGQH series.

• Use all specified fasteners.
• All multiple members must be fastened together to act as a single unit.
• Maximum 11 7/8" bottom chord in the carrying member to allow for the minimum bolt end distance.
• Bolts must be installed symmetrically when using less than 8 bolts on the 8-bolt backplate.
• Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2007 Section 7.5.3.5).
