H Seismic and Hurricane Ties
The Hurricane Tie series features various configurations of wind and seismic ties for trusses and rafters.
The new H2A features an improved design and higher uplift
loads to replace the H2. The new H10A has a similar design as the H10 but offers higher uplift capacity.
The H10S provides a high capacity connection from truss/rafter to stud. A flexible nailing pattern allows installation where the stud is offset from the rafter up to 1". Suitable for wood-to-wood and wood-to-CMU/concrete applications.
The H2.5T's truncated design was developed to accommodate trusses with 2x4 bottom chords. The easy to install, five nail pattern is stronger and gets better uplift loads than our popular H2.5 hurricane tie. H1, H10, H10S, H10-2, H11Z and H14 have also been rated
for download to provide additional bearing capacity between the truss and wall.
The H16-2 series has a presloped seat of 5:12 for double trusses.
The presloped 5/12 seat of the H16 provides for a tight fit and reduced deflection. The strap length provides for various truss height up to a maximum of 13 1/2" (H16 series). Minimum heel height for H16 series is 4".
The HGA10 attaches to gable trusses and provides good lateral wind resistance. The HS24 attaches the bottom chord of a truss or rafter at pitches from 0:12 to 4:12 to double 2x4 top plates. Double shear nailing allows for higher lateral resistance.
See tables.
Galvanized. H7Z and H11Z - ZMAX®. Some models available in stainless steel or ZMAX®; See Corrosion-Resistance.
- Use all specified fasteners. See General Notes.
- H1 can be installed with flanges facing inwards (reverse of H1 drawing number 1).
- H2.5, H2.5T, H3, H4, H5 and H6 ties are only shipped in equal quantities of rights and lefts. (Rights shown.)
- The HGA10KT: screws are provided.
- HS24 requires slant nailing only when bottom chord of truss or rafter has no slope.
- Hurricane Ties do not replace solid blocking.
Considerations for Hurricane Tie Selection
- What is the uplift load?
- What is the parallel-to-plate load?
- What is the perpendicular-to-plate load?
- What is the species of wood used for the rafter and the top plates?
(Select the load table based on the lowest performing species of wood.)
- Will the hurricane tie be nailed into both top plates or the upper top plate only?
- What load or loads will the hurricane tie be taking?*
- Select hurricane tie based on performance, application, installed cost and ease of installation.
*Allowable simultaneous loads in more than one direction on a single connector must be evaluated as follows:
Design Uplift/Allowable Uplift + Design Lateral Parallel to Plate /
Allowable Lateral Parallel to Plate + Design Lateral Perpendicular
to Plate / Allowable Lateral Perpendicular to Plate < 1.0.
The three terms in the unity equation are due to possible directions that
exist to generate force on a hurricane tie. The actual number of terms used
in the equation for each condition is dependant on designer’s method of
calculating wind forces and the utilization of the tie in the structural system.
