THGBV/THGBHV/THGWV SCL-to-Truss Girder Hangers


On This Page

An extension of the THGB/THGBH/THGW series, these high-capacity hangers are designed for attaching two-ply, three-ply or four-ply sized structural composite lumber (SCL) to a girder truss. The THGBV offers optional installation with Strong-Drive® SDS Heavy-Duty Connector screws, while the bolted THGBHV and THGWV offer higher load capacities. Two bucket heights are available for each width to accommodate a range of SCL sizes. Options for skewing or dropping the buckets for conditions where the SCL joist is lower than the girder bottom chord provide additional design flexibility for a variety of SCL-to-truss connections.


  • 3 gauge


  • Simpson Strong-Tie gray paint


  • 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 using fewer than eight bolts on the eight-bolt backplate.
  • Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref. ANSI/TPI 1-2014 Section
  • Shall be attached to a two-ply girder truss to allow for required minimum screw penetration. Strong-Drive SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.


Skewed Seat

  • THGBV/THGBHV hangers can be skewed to a maximum of 45°.
  • The maximum allowable download and uplift load for skew is 0.87 of the table load.

Dropped Bucket

  • THGBV/THGBHV backplates can be extended to allow for up to a 6" dropped bucket.
  • Allowable loads are 100% of the table loads.
  • Order as “X” version, specify the total backplate height, BK_PLT, equal to the hanger height (H) plus the dropped bucket amount (db). Ex: a THGBV3.62/9 with a 4" dropped bucket would have a total backplate height of 27 1/4".

Load Tables

  1. Allowable loads are based on a SCL (LVL, PSL, or LSL) carried member with an allowable F'c ⊥ of 750 psi and equivalent Specific Gravity of 0.50 or higher.
  2. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  3. A three-ply carrying member is required for the THGWV5.50 /9 and THGWV5.50 /11; a four-ply carrying member is required for the THGWV7.25 /9 and THGWV7.25 /11.
  4. Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
  5. 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.
  6. Wind (160) is a download rating.
  7. To achieve published loads, install bolts into the girder truss with the nut on the opposite side of the hanger with a standard-cut washer (except THGWVs). Standard-cut washers are required for THGBV and THGBHV.
  8. Fasteners: Nail dimensions in the table are listed diameter by length. SDS screws are Simpson Strong-Tie® Strong-Drive SDS Heavy-Duty Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
