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.

Material: See tables.

Finish: Galvanized. H7Z and H11Z - ZMAX®. Some models available in stainless steel or ZMAX®; See Corrosion-Resistance.

Installation:

Considerations for Hurricane Tie Selection
  1. What is the uplift load?
  2. What is the parallel-to-plate load?
  3. What is the perpendicular-to-plate load?
  4. 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.)
  5. Will the hurricane tie be nailed into both top plates or the upper top plate only?
  6. What load or loads will the hurricane tie be taking?*
  7. 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.

Both connectors shall be same model.
Install diagonally across from each other for minimum 2x truss. Products can be on the same side of the wall provided they are configured as shown. Nailing into both sides of a single ply 2x truss may cause the wood to split.

top Load Tables: See code report listings below
Table
  1. Loads have been increased 33% and 60% for earthquake or wind loading with no further increase allowed; reduce where other loads govern.
  2. 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 (exception: connectors installed such that nails on opposite sides don’t interfere).
  3. Allowable DF/SP uplift load for stud to bottom plate installation is 400 lbs. (H2.5); 390 lbs. (H2.5A); 360 lbs. (H4) and 310 lbs. (H8). For SPF/HF values multiply these values by 0.86.
  4. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or prevent cross grain bending of the truss or rafter members. Additional shear transfer elements shall be considered where there may be effects of cross grain bending or tension.
  5. Hurricane Ties are shown installed on the outside of the wall for clarity. Installation on the inside of the wall is acceptable (see note u, instructions for the installer). For uplift Continuous Load Path, connections in the same area (i.e. truss to plate connector and plate to stud connector) must be on same side of the wall.
  6. Southern Pine allowable uplift loads for H10A = 1340 lbs. and for H14 = 1465 lbs.
  7. Refer to technical bulletin T-HTIEBEARING for selected hurricane ties allowable bearing enhancement loads.
  8. H10S can have the stud offset a maximum of 1" from rafter (center to center) for a reduced uplift of 890 lbs. (DF/SP), and 765 lbs. (SPF).
  9. H10S nails to plates are optional for uplift but required for lateral loads.
  10. NAILS : 16dx2 1/2 = 0.162" dia. x 2 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8dx1 1/2 = 0.131" dia. x 1 1/2" long. See other nail sizes and information.
Table
  1. Loads have been increased for earthquake or wind loading with no further increase allowed; reduce where other loads govern.
  2. When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist such forces should be considered.
  3. HS24 DF/SP allowable loads without slant nailing are 625 lbs (uplift), 590 lbs (F1), 640 lbs (F2). For SPF/HF loads multiply these values by 0.86.
  4. For H16-2S, S = short.
  5. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or prevent cross grain bending of the truss or rafter members. Additional shear transfer elements shall be considered where there may be effects of cross grain bending or tension.
  6. NAILS: 10dx1 1/2 = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8dx1 1/2 = 0.131" dia. x 1 1/2" long. See other nail sizes and information.
