The Simpson Heavy Embedded Truss Anchor is an engineered connector built to secure roof trusses to concrete and masonry walls where lateral load resistance is critical. Designed specifically for wind and seismic applications, this heavy-duty anchor features a staggered nail pattern that strengthens uplift resistance and a built-in moisture plate that sits above the concrete or masonry wall surface, helping protect structural members from moisture damage at the connection point. With a 15-in. exposed length and a 5-1/16-in. embed depth into a poured concrete bond beam or grouted block wall, the Simpson truss-to-wall anchor delivers reliable, code-conscious performance in demanding residential and commercial framing applications.

Key Features

• Installs straight or field-bent around truss or rafter members - gives installers on-site flexibility to accommodate varying framing configurations without special tools or additional hardware.
• Built-in moisture barrier sits above the concrete or masonry wall - protects the truss seat and adjacent framing from moisture intrusion at the wall-to-roof connection, supporting long-term structural integrity.
• Load rated for wind and seismic forces - engineered to meet lateral load demands in high-wind and seismic zones, helping projects satisfy structural code requirements.
• 15-in. exposed length - provides sufficient strap length to make a secure, full-depth connection to the truss or rafter member above the wall plane.
• Embeds 5-1/16 in. into a poured concrete bond beam or grouted block wall - achieves rated load capacity when properly set at the specified depth, ensuring the anchor performs as engineered.
• Strap made from 16-ga. steel; truss seat made from 18-ga. steel - a heavier-gauge strap handles the lateral strap loads while the appropriately gauged seat supports the truss bearing point, balancing strength where it matters most.
• Zinc Galvanized, G90 coating - provides extra corrosion resistance for exposure to the moisture and alkalinity common in concrete and masonry wall assemblies.

Why This Product

• Purpose-built for lateral load applications - unlike general-purpose truss connectors, this anchor is specifically engineered to resist the lateral forces generated by wind and seismic events, making it the right tool for code-required connections in demanding structural conditions.
• Installs into the most common masonry wall types - compatible with both poured concrete bond beams and grouted concrete block walls, covering the two wall assemblies most frequently encountered in concrete and masonry construction.
• Built-in moisture protection at the most vulnerable point - the integrated moisture barrier addresses a common failure point in wall-to-roof connections, reducing the risk of moisture-related degradation without requiring a separate barrier component.
• Field-adjustable strap saves time on the job - the ability to bend the strap on site around the truss or rafter member means contractors can adapt the anchor to real-world framing conditions without returning to the supply house for a different part.

Frequently Asked Questions

How deep does the HETAL20 need to be embedded into the wall?

The HETAL20 must be embedded 5-1/16 in. into either a poured concrete bond beam or a grouted concrete block wall to achieve its rated load capacity.

What fasteners are recommended for installing the HETAL20?

The HETAL20 is designed to be installed with 10d x 1-1/2 in. nails or 16d common nails for connecting the anchor to the truss or rafter member.

Can the HETAL20 strap be bent on the job site to fit around a truss or rafter?

Yes. The strap can be installed straight or field-bent around truss or rafter members, providing installation flexibility to accommodate different framing configurations.

What protection does the HETAL20 offer against moisture damage?

The HETAL20 features a built-in moisture barrier that sits above the concrete or masonry wall surface, helping to protect the truss or rafter member from direct contact with moisture at the wall. The anchor is also coated with a G90 zinc galvanized finish for extra corrosion resistance.
