The Simpson MTS18 18" 16-Gauge Galvanized Medium Twist Strap is an economical structural connector from Simpson built to deliver a reliable tension connection between two framing members. Designed to resist moderate uplift loads at the rafter or heel of a truss, this twist strap features a 2-in. bend section that reduces interference at transition points between members, making it a practical choice for rafter tie-down and truss heel connections in residential and light commercial framing.

Key Features

• 2-in. bend section - reduces interference at transition points between members, resulting in a cleaner, more practical installation without awkward repositioning
• No wrapping required - straps do not need to be wrapped over the truss to achieve the allowable load, saving time and simplifying the fastening process
• Reversible bend option available - the bend can be ordered reversed to accommodate varying framing orientations, giving installers greater flexibility on the job
• Multiple lengths offered - a wide range of sizes lets you select the exact length for your specific application, reducing waste and guesswork
• 16-gauge steel construction - provides the structural integrity needed to resist moderate uplift forces at rafters and truss heels
• G90 zinc galvanized finish - delivers enhanced corrosion resistance, helping the strap maintain performance in moisture-exposed framing environments

Why This Product

• Engineered for uplift resistance without overcomplication - the MTS18 resists moderate uplift loads at the rafter or heel of a truss without requiring the strap to wrap over the truss, keeping installation straightforward and code-compliant
• Built-in versatility for real job-site conditions - with the option to specify a reversed bend, this strap adapts to different framing configurations rather than forcing a workaround on site
• Corrosion-resistant coating for long-term reliability - the G90 zinc galvanized finish protects the steel in conditions where moisture exposure is a concern, supporting the long-term integrity of the connection
• Made in the United States to Simpson quality standards - domestic production supports consistent manufacturing quality for a structural connector that builders and contractors depend on for uplift tie-down applications
