Product Details
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 masonry wall for easy installation of drywall. The LGT connector also provides exceptional bearing enhancement for heavy download applications.
Key Features
- Suitable for retrofit applications
- Embossments that 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
- Use all specified fasteners; see General Notes
- Connectors attached using Titen Turbo™ screws shall have hex heads
- To achieve the loads listed in the table below, the product shall be attached to a grouted and reinforced block wall or a reinforced concrete wall designed by others to transfer the high concentrated uplift loads to the foundation
- 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
- Products shall be installed such that Titen Turbo screws and non-stainless Titen HD® anchors are not exposed to the exterior environment

- Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
- Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
- Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
- LGT2 â F1 load = 700 lb.; F2 load = 170 lb.; LGT3 — F1 load = 795 lb.; F2 load = 385 lb.; LGT4 — F1 load = 2,000 lb.; F2 load = 675 lb.
- For concrete wall applications, use 1/4" x 1 3/4" Titen Turbo screws.
- 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 7.5.3.4 and 8.9.2 are met (predrilling required through the plate using a 5/32" bit maximum).
