H1.81Z Hurricane Tie

H1.81Z

On This Page

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

Material

  • 18 ga.

Finish

  • ZMAX®

Installation

  • 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. 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 Wood Construction Connectors catalog General Instructions for the Installer, note "p"). 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. See technical bulletin T-C-HTIECON for more information.
  5. 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.
