LGT Light Girder Tiedown

Girder Tiedowns for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Girder Tiedowns for Plated Truss. You can also view product information related to the categories of: Girder Tiedowns, Girder Tiedowns for Masonry

The LGT is a connector designed to resist light to moderate uplift loads of multi-ply trusses. This light girder tiedown provides a low-profile connection to the studs for easy installation of drywall. The LGT connector also provides exceptional bearing enhancement for heavy download applications.

Key Features

  • Suitable for retrofit applications
  • The embossments add stiffness in crucial areas for improved performance
  • Simple to install and can be installed on the inside or outside of the wall
  • Load rated to resist high-wind forces


  • LGT2 — 14 gauge; LGT3/LGT4 — 12 gauge


  • Galvanized (G90). Some models availabale in HDG; see Corrosion Information.


  • Before installing fasteners, ensure LGT3-SDS2.5 makes complete contact with bottom of truss
  • Connectors attached using Titen Turbo™ screws shall use hex head models
  • LGT3-SDS2.5 — the four large hexagon holes are intended for GFCMU and concrete applications

Load Tables

    These products are available with additional corrosion protection.

  1. See Straps and Ties General Notes.
  2. LGT2 — F2 load requires installation of (4) 0.148" x 3 1/4" sinkers or four #9 x 1 1/2" SD Connector screws (SD) in optional nail holes.
  3. LGT4 — F2 load requires installation of (7) 0.148" x 3 1/4" sinkers in optional nail holes.
  4. LGT4 — Uplift for DF/SP girder and SPF studs is 3,860 lb.
  5. LGT connectors can provide bearing enhancement loads for truss download reactions. For more information, refer to technical bulletin T-C-HTIEBEAR.
  6. LGT2 installed with #9 x 1 1/2" SD Connector screws (SD) will achieve double the uplift load when installed on opposite sides of the top plates, but on separate truss members. See typical back-to-back LGT2 installation detail. Lateral loads may not be doubled.
  7. Girder tiedowns installed on the outside of the wall require a 3 1/2" overhang to achieve table loads.
  8. Strong-Drive SDS Heavy-Duty Connector screws may be installed through metal truss plates as approved by the truss designer, provided the requirements of ANSI/TPI 1-2014, Sections and 8.9.2 are met (predrilling required through the plate using a 5/32" bit maximum).
  9. The allowable uplift load listed is for the girder tiedown and anchor rods only. The allowable uplift of the holdown or other anchorage must be checked.
  10. Fasteners: Nail dimensions in the table are listed diameter by length. SD and SDS screws are Simpson Strong-Tie® Strong-Drive screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
