The Simpson MTS20 20" 16-Gauge Galvanized Medium Twist Strap is an economical structural connector engineered to deliver a reliable tension connection between two members, resisting moderate uplift loads at the rafter or heel of a truss. Its 2-in. bend section reduces interference at the transition points between members, keeping installations clean and precise whether you are securing rafters or working at truss heel connections.

Key Features

• 2-in. bend section reduces transition interference - minimizes obstruction where two members meet, resulting in cleaner, more precise installations without awkward fitment issues
• Straps do not need to be wrapped over the truss to achieve the allowable load - simplifies the installation process and saves labor time on the job site
• Available with the bend reversed - gives installers flexibility to orient the strap to match the specific framing configuration, reducing the need for workarounds
• Offered in many lengths to fit the specific application - lets contractors select exactly the right size for the project rather than forcing a one-size-fits-all solution
• Made from 16-gauge steel - provides the structural integrity needed to handle moderate uplift demands at rafters and truss connections
• Zinc Galvanized G90 coating - delivers extra corrosion resistance for long-term durability in exposed or demanding environments

Why This Product

• No truss wrapping required - the MTS20 achieves its allowable load without being wrapped over the truss, streamlining installation and reducing hands-on effort compared to straps that demand full wrap-around placement
• Built-in flexibility for real-world framing conditions - the option to reverse the bend direction means the strap adapts to varying rafter and truss configurations, making it a practical choice for jobs where standard orientation will not work
• Corrosion resistance you can count on - the G90 galvanized finish protects the steel against moisture and environmental exposure, supporting long-term performance in roof framing applications where durability matters
• Economical tension connection solution - designed to resist moderate uplift loads at the rafter or heel of a truss without over-engineering the connection, giving builders a cost-effective option that still meets structural demands
