On This Page

The THGW is an extra-high-capacity bolted hanger designed for installing multi-ply girder trusses. This welded hanger attaches to a vertical web and features a unique wraparound shape that supports higher loads with a double-shear design.

  • Simpson Strong-Tie gray paint. HDG available; see Corrosion Information.


  • Use all specified fasteners; see General Notes
  • 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 fewer than the maximum number of bolts are used on the backplate
  • Girders must have adequate lateral bracing to prevent excessive displacement due to secondary torsional stresses (refer to ANSI/TPI 1-2014 Section

Load Tables

THGW Truss and SCL-to-Truss Girder Hangers Load Table
  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. A three-ply carrying member is required for the THGW3-3 and THGW4-3; a four-ply carrying member is required for the THGW3-4 and THGW4-4. For all other models, a minimum two-ply carrying member is required.
  3. Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
  4. Bolts and Strong-Drive SDS Heavy-Duty Connector screws (not included) may be installed through metal truss connector plates as approved by the truss designer, provided the requirements of ANSI/TPI 1-2014, Sections and 8.9.2 are met.
  5. (10) 0.148" x 3" nails for the carried member will achieve the maximum downloads. Uplift loads are 2,570 lb. for DF/SP and 2,210 lb. for SPF/HF. To achieve maximum uplift, install nails and bolts listed in the table.
  6. Loads for THGW models require that the supported member have minimum 2x6 end verticals to ensure end-grain bearing. Contact Simpson Strong-Tie for loads when horizontal members are bearing in the hanger seat.
