Hurricane Ties for Masonry

This product's information may differ depending on the category of use. You are currently viewing details related to Hurricane Ties for Masonry. You can also view product information related to the categories of: Seismic and Hurricane Ties, Hurricane Ties for Plated Truss, Roof Truss and Rafter Connectors, Ties, and Straps for Cold-Formed Steel Construction

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 Titen® 2 concrete and masonry screws.

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".

H/LTA2 Seismic and Hurricane Ties / Lateral Truss Anchor Load Table
  1. Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
  2. HGAM10KTA 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.
  3. Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
  4. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  5. The HM9KT and HGAM10KTA are kits with (20) HM9 and (10) HGAM10 connectors packaged with Strong-Drive® SDS Heavy-Duty Connector screws and 2 1/4" and 2 3/4" Titen® 2 screws, respectively. (1 3/4" Titen 2 screws for concrete installations sold separately.)
  6. See Titen® 2 screw information.
  7. Products shall be installed such that the Titen® 2 screws and Titen HD® screw anchors are not exposed to the weather.
  8. HGAM10 F2 loads are for forces into the connector. F2 loads away from the connector are 640 lb. (DF/SP) and 460 lb. (SPF/HF).
