The Simpson LSTA18 1-1/4 in. x 18 in. 20-Gauge Galvanized Strap Tie is a load-rated, precut light strap tie engineered by Simpson to resist tension loads in wood-to-wood applications. Designed specifically for use on the edge of 2x members, it features a staggered nail pattern that helps minimize wood splitting during installation - making it a dependable solution for floor-to-floor clear span connections where wind and seismic resistance are critical requirements.

Key Features

• Load-rated, precut strap - arrives ready to install with no cutting or sizing required, saving time on the job site and ensuring consistent, engineered performance
• Staggered nail pattern - strategically positioned fastener holes help minimize wood splitting when securing to 2x members, protecting the integrity of the connection
• Designed to resist wind and seismic forces - provides reliable structural performance in applications where lateral and tension loads must be addressed
• Floor-to-floor clear span application - bridges framing members across open spans, making it well suited for multi-story structural connections
• 20-gauge steel construction - delivers a strong yet workable strap that installs cleanly with common fasteners including 10d common nails or #9 x 1 1/2 in. Strong-Drive SD screws
• G90 zinc galvanized coating - provides extra corrosion resistance for lasting durability in demanding construction environments
• 1-1/4 in. width x 18 in. length - compact proportions sized for edge applications on 2x framing members without excess material

Why This Product

• Engineered specifically for edge-of-member use - unlike generic strap ties, the LSTA18 is purpose-designed for installation on the edge of 2x members, ensuring the connection geometry works with standard framing rather than against it
• Splitting protection built into the design - the staggered nail pattern is not an afterthought but a core design feature, reducing the risk of damaging the wood during fastening and preserving full structural capacity
• Wind and seismic rated for code-sensitive projects - the load-rated design supports compliance in regions where wind and seismic performance requirements apply to structural strap connections
• G90 galvanized finish for long-term reliability - the corrosion-resistant coating helps the strap maintain its structural integrity over time, even in conditions where moisture exposure is a concern
