The Simpson HETAL Heavy Embedded Truss Anchor delivers an engineered solution for securing roof trusses to concrete and masonry walls where lateral load performance is critical. Designed to handle wind and seismic forces, this heavy-duty anchor features a staggered nail pattern that strengthens uplift resistance and a built-in moisture plate positioned above the concrete or masonry wall to protect the connection point. The ZMAX galvanized finish provides enhanced corrosion resistance, making this truss anchor well suited for exterior construction and applications involving treated wood.

Key Features

• Can be installed straight or field-bent around truss or rafter members - gives installers flexibility to adapt the anchor to existing framing conditions without additional hardware.
• Built-in moisture barrier - sits above the concrete or masonry wall to help protect the connection from water intrusion at the embed point.
• Load rated for wind and seismic forces - provides confidence that the connection meets engineered performance requirements for lateral load applications in demanding structural environments.
• Strap made from 16-ga. steel; truss seat made from 18-ga. steel - the dual-gauge construction balances strength in the strap with the appropriate rigidity in the seat for a reliable truss-to-wall connection.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - extends the service life of the anchor when exposed to the elements or in contact with pressure-treated lumber.
• Embeds into a poured concrete bond beam or grouted block wall - compatible with two common masonry wall assemblies, broadening the range of projects where this anchor can be specified.

Why This Product

• Engineered specifically for lateral loads - unlike general-purpose truss ties, this anchor is purpose-built to resist the lateral forces generated by wind and seismic events, making it the right choice when code-compliant performance at the truss-to-wall connection is required.
• ZMAX coating adds a layer of long-term protection - the extra corrosion resistance provided by ZMAX galvanization means the anchor holds up in exterior conditions and alongside treated-wood framing, where standard galvanized connectors may fall short over time.
• Installation flexibility reduces field complications - the ability to install the anchor straight or field-bent around truss or rafter members means crews can work with the framing as it sits rather than forcing alignment, saving time and reducing the risk of improper installation.
• Integrated moisture plate addresses a common weak point - having the moisture barrier built directly into the anchor eliminates the need for a separate barrier component at the wall-to-truss interface, simplifying the assembly and reducing the chance of that detail being overlooked on the job site.
