Hurricane Ties for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Hurricane Ties for Plated Truss. You can also view product information related to the category: Seismic and Hurricane Ties

The new H1.81Z hurricane tie is designed for use with 1 3/4" LVL roof rafters to provide a stronger connection to the top plate of the wall. It's ideal for connections when there are higher-load demands on the structure, like a heavy snow load, and provides lateral resistance in a seismic event.

The 1 3/4"-wide H1.81Z connector is the first hurricane tie to be specifically sized for engineered wood. The H1.81Z installs with half the nails that are needed for two single-sided twist straps, like the H2.5A, and offers a higher lateral allowable load, making it a cost-effective and higher-performing solution to tie down an LVL roof.

Key Features

  • Wider seat to fit 1 3/4" LVL rafters
  • Both side faces connect to the joist for better support
  • Can be installed on inside or outside of wall, or both sides
  • Connector embossments add stiffness in crucial areas for improved performance
  • Fits popular 0.148" x 1 1/2" connector nails


  • 18 ga.


  • ZMAX®


  • Use all specified fasteners; see General Notes
  • Ties can be installed with flanges facing inward or outward
  • Hurricane ties do not replace solid blocking
  • Installation on the outside or inside of wall is acceptable

  1. Loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  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 tension cannot be avoided in the members, mechanical reinforcement to resist such forces may be considered.
  4. H1.81Z shown on the outside of wall assumes a min. overhang of 3 1/2". Installation on the inside of wall is acceptable with detailing for the uplift continuous load path by Designer.
  5. For parts installed on the outside of wall where only three plate fasteners can be accessed, reduce table loads by 0.75 for single part and 0.875 for two-part installations.
