Simpson Strong-Tie HHETA18 - 14" Embedded Truss Anchor
Girder Tiedowns for Masonry
The HHETA provides an engineered method to attach roof trusses securely to concrete and masonry walls. This extra-heavy embedded truss anchor features staggered nail patterns to strengthen uplift resistance and can be used in pairs on single- and multi-ply trusses. The versatile HHETA can be installed straight or field-bent around truss or rafter members.

Installation
- Use all specified fasteners.
- Embedded 4" into a 6" min. concrete beam or 8" nominal grouted block wall.
- 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.
- In double anchor installations, install anchors with spoons facing outward and straps spaced no more than 1/8" wider than the rafter/truss width. Do not install nails where the straps overlap when wrapped over the rafter/truss.
- Straps do not need to be wrapped over the rafter/truss to achieve tabulated loads, unless noted otherwise.
