H Seismic And Hurricane Ties / LTA1 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 LTA1 develops high uplift and lateral loads at a minimum heel height. The side tabs act as a locator in the block and the four embedded hooks allow for higher loads with a relatively shallow embedment.

Material: See table.

Finish: Galvanized; see Corrosion Information.

Installation:

Use all specified fasteners. See General Notes.
Connectors attached using hex head Titen® screws.
Attach to grouted concrete block with a minimum one #5 rebar horizontal in the course.
Hurricane Ties do not replace solid blocking.

Loads have been increased 60% 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 packaged with Simpson Strong-Tie® Strong-Drive® screws (SDS)and 2 1/4" and 2 3/4" Titen® screws respectively. (1 3/4" Titen® screws for concrete installations sold separately.)
Minimum edge distance 1 1/2" using Titen® screws.
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 2 for loads away from the connector.
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.
