H/LTA2 Seismic and Hurricane Ties/Lateral Truss Anchor for Masonry
The Hurricane Tie series features various configurations of wind and seismic ties for trusses and rafters.
The H10S provides a high capacity connection from truss/rafter to wall. Also suitable for wood-to-wood applications.
The HM9 is designed to retrofit roof truss/rafters for block construction. The HM9 hurricane tie provides high uplift and lateral capacity using Simpson Strong-Tie® concrete fasteners.
The presloped 5/12 seat of the H16 provides for a tight fit and reduced deflection. The strap length provides for various truss heights up to a maximum of 13 1/2". Minimum heel height for H16 series is 4".
The new LTA2 is an embedded truss anchor for grouted CMU and concrete walls that develops high loads with shallow embedment. Designed for 2x4 minimum truss chords, the LTA2 resists uplift and lateral loads parallel and perpendicular to the wall with a minimum heel height requirement.
- Simplified design of the embedded portion allows for easy positioning close to rebar
- Ideal for anchoring trusses running perpendicular or parallel to the wall
- Embedment line stamped on part simplifies installation and helps avoid installation errors
H Ties—see table; LTA2—18 gauge
Galvanized. See Corrosion Information.
- Use all specified fasteners. See General Notes.
- Connectors attached using hex head Simpson Strong-Tie® Titen® screws.
- Attach to grouted concrete block with a minimum one #5 rebar horizontal in the course.
- Hurricane Ties do not replace solid blocking.
- Whether in grouted CMU or concrete, the LTA2 must be embedded to the depth of the embedment line stamped on the part.
- A minimum of one horizontal #5 rebar is required at top of concrete or in the top course of grouted CMU.
- For parallel-to-wall applications, install the LTA2 with flanges facing the center of the wall. Minimum edge distance of 1 1/2" required.

- Loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
- Allowable loads are for one anchor. A minimum rafter thickness of
2 1/2"must be used when framing anchors are installed on each side of the joist and on the same side of the plate.
- The HM9KT and HGAM10KTA are kits with (20) HM9 and (10) HGAM10 connectors packaged with Simpson Strong-Tie® Strong-Drive® SDS screws and 2 1/4" and 2 3/4" Titen® screws respectively. (1 3/4" Titen® screws for concrete installations sold separately.)
- See Titen® screw information.
- Table allowable loads were determined using test ultimate/3 or fastener calculation values.
- Products shall be installed such that the Titen screws and Titen HD® anchors are not exposed to the weather.
- HGAM10 F2 loads are for forces into the connector. See illustration "HGAM10 Installed into Masonry" for loads away from the connector.
- LTA2 allowable uplift on SP is 1425 lbs. for perpendicular to wall installation and 1390 lbs. for parallel to wall installation.
- NAILS: 10dx1 1/2 = 0.148" dia. x 1 1/2" long. 8dx1 1/2 = 0.131" dia. x 1 1/2" long. See other nail sizes and information.
