H1/H1.81Z Hurricane Ties

H1/H1.81Z

On This Page

The H1 and H1.81Z provide a connection between the truss or rafter and the wall of the structure that helps resist wind and seismic forces. The H1.81Z hurricane tie is designed specifically for use with 1 3/4" LVL roof rafters, and the H1 is designed for nominal 2x lumber. These U-shaped hurricane ties provide faster installation than using two single-sided ties. The embossments add stiffness in crucial areas for improved performance.

Key Features

  • Holds the rafter or truss on both sides for high lateral load resistance
  • Used for a variety of connections where one member crosses another
  • Can be installed on inside or outside of wall, or both sides
  • Can be installed with flanges facing either inward or outward

Material

  • 18 ga.

Finish

  • Galvanized (G90) or ZMAX® coating; see Corrosion Information

Installation

  • Use all specified fasteners; see General Notes.
  • Hurricane ties do not replace solid blocking.
  • When installing ties on plated trusses (on the side opposite the truss plate) do not fasten through the truss plate from behind. This can force the truss plate off of the truss and compromise truss performance.

H/TSP Seismic and Hurricane Ties Load Table
  1. See General Notes for Straps and Ties.
  2. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or cross-grain bending of the truss or rafter members.
  3. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces shall be considered by the designer.
  4. Hurricane ties are shown on the outside of the wall for clarity and assume a minimum overhang of 3 1/2". Installation on the inside of the wall is acceptable (see General Instructions for the Installer). For uplift continuous load path, install connectors in the same area (e.g., truss-to-plate connector and plate-to-stud connector) on the same side of the wall, unless detailed by designer.
  5. Refer to Simpson Strong-Tie® technical bulletin T-C-HTIEBEAR for allowable bearing enhancement loads.
  6. 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.
