A dedicated range of Top Flange I-joist hangers meeting the unique needs of I-joists while offering superior performance and ease of installation.

ITS
NEW! The innovative ITS sets a new standard for engineered wood top flange hangers. The ITS installs faster and uses fewer nails than any other EWP top flange hanger. The new Strong-Grip™ seat and Funnel Flange™ features allow standard joist installation without requiring joist nails resulting in the lowest installed cost. The Strong-Grip™ seat firmly secures I-joists with flange thicknesses from 1 1/8" to 1 1/2". The ITS design maintains superior allowable download capacities equal to or greater than the ITT for Douglas Fir and all SCL headers

ITT
The ITT’s special bend-tabs constrains the I-joist, helping to reduce squeaks resulting from joist movement. I-joist flange thickness for bend-tab application is 1 1/8" to 1 1/2".

MIT/HIT - Patented Positive Angle Nailing (PAN)
PAN is specifically designed for I-joists when used with the MIT or HIT. With PAN, the nail hole material is not removed, but is formed to channel and confine the path of the nail at approximately 45°. PAN minimizes splitting of the flanges while permitting time-saving nailing from a better angle.

See Top Flange tables.

Refer to Joist Manufacturer's literature or appropriate Simpson Strong-Tie Connector Selection Guide for actual joist sizes.

Step 1
Attach the ITS to the header
Step 2
Slide the I-joist downward into the ITS until it rests above the Strong-Grip™ seat.
Step 3
Firmly push or snap I-joist fully into the seat of the ITS.

Correct Nailing Approx. 45° angle Nail too long Nail at wrong angle
Toe-Nailing
Toe nailing causes squeaks and improper hanger installations. Do not toe nail I-joists before installing top flange or face mount hangers.

top Wood I-Joists:
 

Sloped Joists
For sloped joists up to 1/4:12 there is no reduction. For slopes greater than 1/4:12 see individual product pages or refer to technical bulletin T-SLOPEJST.

Multiple Joists
Multiple joists should be adequately connected together to act as one unit.

Fasteners
Use the correct nails. Wood may split if the nails are too large. Hanger nails into flanges should not exceed 10d common (0.148 dia.), no longer than 1 1/2". Nails into web stiffeners should not exceed 16d commons (0.162 dia.).

Eccentrically-Loaded I-Joists
Supporting a top flange hanger may require bottom flange restraining straps, blocking or directly-applied ceiling systems to prevent rotation at the hanger location.

Skewed Joists
Joists may be skewed up to 2 1/2 degrees in a non-skewed hanger without any load reduction. Refer to individual hanger descriptions for information allowing any further skew applications.

I-JOIST AS A HEADER INSTALLATIONS
 
  Face Mount Hanger Top Flange Hanger
Backer block nails not shown for clarity
 
When face mount hangers are attached to I-joist headers, backer blocks must be installed to provide a nailing surface for the hanger nails. The backer blocks should be installed on both sides of the web and attached together with a minimum of 10-10d nails. The hanger nails should extend through the web. Contact the I-Joist manufacture for additional design considerations.
When top flange hangers are attached to I-joist headers, a backer block must be installed to prevent the top flange from rotating under load. The backer blocks should be installed with a minimum of 10-10d nails clinched. Check with the joist manufacture for additional design considerations.
     
   
 
top IT Series With Various Header Applications:See code report listings below
Table

Also see ITTM Series for concrete and masonry installations.

  1. Uplift loads are based on DF/SP lumber and have been increased 60% for wind or earthquake loading with no further increase allowed. For normal loading applications such as cantilever construction refer to Simpson Strong Tie® Connector Selector™ software or conservatively divide the uplift load by 1.6. For SPF/HF use 0.86 x DF/SP uplift load.
  2. Applies to LVL headers made primarily from Douglas Fir or Southern Pine. For LVL made primarily from Spruce Pine Fir or similar less dense veneers, use the values found in the SPF/HF column.
  3. DF I-joists include flanges made from solid sawn Douglas Fir, LVL made primarily of Douglas Fir/Southern Pine, or LSL. For flanges with thicknesses from 1 5/16 to 1 3/8, use 0.85 of the I-joist header load. For flanges with thicknesses from 1 1/8 to 1 1/4, use 0.75 of the I-joist header load.
  4. SCL (structural composite lumber) is LVL, LSL, and Parallam® PSL.
  5. Web stiffeners required for the ITS Alternate Installation when installing optional joist nails for additional uplift load.
  6. Code Values are based on DF/SP header species.
  7. I-joists with flanges less than 1 5/16" thick used in combination with hangers thinner than 14 gauge may deflect an additional 1/32" beyond the standard 1/8" limit.
  8. For 2 1/2" and 2 7/16" wide joists, see top flange hanger tables for allowable loads.

top Nailer Table:

This table indicates various allowable loads for ITS/ITT/MIT/HIT hangers used on wood nailers. The header nail type must be substituted for those listed in other tables. See technical bulletin T-NAILERUPLFT for other uplift values and options.

NAILS: 16d = 0.162" dia. x 3 1/2" long, 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. See other nail sizes and information
Table
  1. These hangers may deflect an additional 1/32" at design load.
  2. Uplift loads are based on DF/SP members only.
top Optional Nailing For Increased Uplift:
Table
  1. Loads are based on Douglas Fir, and have been increased 60% for wind or earthquake loading with no further increase allowed. Reduce according to the code for normal loading criteria such as in cantilever construction.
  2. Web stiffeners are required on I-joist for additional nailing.
