Typical MTS30 Installation

MTS30 Installation with I-joist Rafter

Twist straps provide a tension connection between two wood members. They resist uplift at the heel of a truss economically. The 3" bend section eliminates interference at the transition points between wood 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.

Some products may be installed with the Strong-Drive® SD Structural Connector screw - click here for details

These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

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

Loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
LTS12 thru LTS20, MTS16 through MTS30, HTS24 through HTS30C (except HTS30) have additional nail holes.
Install half of the fasteners on each end of strap to achieve full loads.
All straps except the MTS30 and HTS30 have the twist in the center of the strap.
Twist straps do not have to be wrapped over the truss to achieve the load.
May be installed on the inside face of the stud.
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.
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.
