Description
Twist straps provide a tension connection between two wood members. They resist uplift at the heel of a truss economically. LTS/MTS have a 2"-bend section, and HTS has a 3 3/4"-bend section that eliminates interference at the transition points between the two members.
Material
- LTS — 18 gauge; MTS — 16 gauge; HTS — 14 gauge
Finish
- Galvanized. Some products available in stainless steel and ZMAX®; see Corrosion Information.
Installation
- Use all specified fasteners; see General Notes.
- LTS, MTS and HTS are available with the bend reversed. Specify "-REV" after the model number, such as MTS16-REV.
