Product Details
The HETAL provides an engineered method to attach roof trusses securely to concrete and masonry walls. This heavy embedded truss anchor works specifically to support lateral loads and features a staggered nail pattern to strengthen uplift resistance. The HETAL also features a built-in moisture plate that sits above the concrete or masonry wall.
Key Features
- The strap can be installed straight or field-bent around truss or rafter members
- Built-in moisture barrier
- Load rated for wind and seismic forces
Material
- Strap 16 gauge, truss seat 18 gauge
Finish
- Galvanized. Some products available in ZMAX® coating. See Corrosion Information.
Installation
- Use all specified fasteners; see General Notes.
- Embedded 5 1/16".
- For mislocated truss anchors which are greater than 1/8" but less than 1 1/2" from the face of the truss, a shim must be provided. Shim design by truss engineer. When gap is greater than 1 1/2", abandon existing embedded truss anchor and install new anchor per designer.
- Minimum spacing of single anchors is twice the embedment depth for full load. For closer spacing, see loads for double anchor installation.
- For lateral loads listed, the lowest four nail holes must be filled.
- Straps do not need to be wrapped over the rafter/truss to achieve tabulated loads, unless noted otherwise.

Load Tables
These products are available with additional corrosion protection.
- Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
- Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
- Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
- For simultaneous loads in more than one direction, the connector must be evaluated using either the Unity Equation or the 75% Rule, as described in Straps and Ties General Notes.
- F1 lateral load toward face of HETAL is 1,870 lb.
- The HETAL requires five nails installed in the truss seat.
- It is acceptable to use a reduced number of fasteners provided that there is a reduction in uplift allowable load. Calculate the connector allowable load for a reduced number of nails as follows: Allowable Load = (No. of Nails Used) / (No. of Nails in Table) x Table Load.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
