The Simpson META18 Galvanized Embedded Truss Anchor from Simpson delivers an engineered, load-rated solution for anchoring roof trusses securely to concrete and masonry walls. Built from 18-gauge steel with a G90 galvanized coating, this medium embedded truss anchor is designed and tested to meet the demands of both wind and seismic loading conditions - giving contractors and builders a reliable, code-conscious connection between roof framing and structural walls. Its versatile design allows for straight installation or field-bending around truss or rafter members, making it adaptable to a wide range of residential and light commercial roofing applications.

Key Features

• Indented embedment line - takes the guesswork out of installation by giving you a clear, built-in reference mark for accurate embed depth every time
• Load rated for wind and seismic forces - provides documented, engineered performance data so your roof-to-wall connection meets structural and code requirements in high-stress environments
• Staggered nail patterns - specifically engineered to strengthen uplift resistance, reducing the risk of connection failure during high-wind or seismic events
• Can be installed straight or field-bent - adapts to your framing layout on-site without additional hardware, saving time and reducing material waste
• Usable in pairs on single- and multi-ply trusses - gives you flexibility across a variety of truss configurations without needing a different anchor product
• 18-gauge steel with G90 galvanized coating - the zinc galvanized finish provides extra corrosion resistance, extending the service life of the connection in moisture-prone wall assemblies
• Compatible with the Simpson TSS truss seat snap-in and TBP8 moisture barrier plate - integrates seamlessly with companion accessories for a complete, system-level truss-to-wall connection

Why This Product

• Engineered for demanding load conditions - the META18 is load rated for both wind and seismic forces with staggered nail patterns that actively strengthen uplift resistance, making it a dependable choice for truss anchoring in structurally critical applications
• Built-in accuracy aids faster, more consistent installation - the indented embedment line eliminates measuring errors at the wall, helping crews embed the anchor to the correct depth quickly and confidently across multiple placements
• Versatile enough to handle a wide range of installations - compatible with single- and multi-ply trusses and installable straight or field-bent, this anchor adapts to different framing scenarios without requiring additional connector types on the job
• G90 galvanized finish supports long-term connection integrity - the zinc galvanized coating provides extra corrosion resistance to help protect the anchor's structural performance over time in concrete and masonry wall assemblies
