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

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

Material

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

Finish

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

Installation

  • Before installing fasteners, ensure LGT3-SDS2.5 makes complete contact with bottom of truss
  • Strong-Drive® SDS Heavy-Duty Connector screws included with LGT3 and LGT4
  • LGT3-SDS2.5 — the four large hexagon holes are intended for GFCMU and concrete applications
