LTS/MTS/HTS Twist Straps

LTS/MTS/HTS

Twist Straps

This product's information may differ depending on the category of use. You are currently viewing details related to Twist Straps. You can also view product information related to the category: Roof Truss and Rafter Connectors, Ties, and Straps for Cold-Formed Steel Construction

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® coating. 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.
  • Some products may be installed with the Strong-Drive® SD Connector screw. See model table.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

MTS30 Installation with I-joist Rafter
  1. Loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  2. LTS12 thru LTS20, MTS16 through MTS30, HTS24 through HTS30C (except HTS30) have additional nail holes.
  3. Install half of the fasteners on each end of strap to achieve full loads.
  4. All straps except the MTS30 and HTS30 have the twist in the center of the strap.
  5. Twist straps do not have to be wrapped over the truss to achieve the load.
  6. May be installed on the inside face of the stud.
  7. Allowable lateral loads are F1 = 75 lbs. and F2 = 125 lbs. when the following installation requirements are met. The first 7 nail holes each side of the bend must be filled with 10dx1 1/2 minimum nails. All additional fasteners may be installed in any remaining strap holes.
  8. NAILS: 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
