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
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".

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 Hanger tables.

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

Material: ITS—18 gauge; MIT, HIT—16 gauge

Finish: Galvanized

Installation:

Use all specified fasteners. Verify that the header can take the required fasteners specified in the table.
See product specific installation drawings.
ITS - no joist nailing required for standard I-joist installation without web stiffeners. When supporting I-joists with web stiffeners or rectangular SCL member 2-10dx1 1/2" must be installed into optional triangle joist nail holes for standard installation values.
ITS - optional triangle nail holes may be used for additional load. See Optional Nailing For Increased Uplift table. See allowable load tables. Refer to technical bulletin T-OPTUPLIFT for additional options.
MIT - optional triangle nail holes may be used for increased uplift capacity. See Optional Nailing For Increased Uplift table.
HIT - closed PAN nail holes may be used for increased uplift capacity. See Optional Nailing For Increased Uplift table.
For sloped joists up to 1/4:12 there is no reduction; between 1/4:12 and up to 1/2:12, tests show a 10% reduction in ultimate hanger strength. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type.

Allowable Loads:

The ITS, MIT and HIT hangers have locations for optional nails if additional uplift is needed. Optional uplift nailing requires the addition of properly-secured web stiffeners. See the load tables for minimum required fasteners and allowable uplift loads.

Options:

Because these hangers are fully die-formed, they cannot be modified. However these models will normally accommodate a skew of up to 5°.
Joining multiple plies.

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.

I-JOIST AS A HEADER INSTALLATIONS

	Face Mount Hanger	Top Flange Hanger

	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 manufacturer for additional design considerations.

Uplift loads are based on DF/SP lumber and have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern. For SPF/HF use 0.86 x DF/SP uplift load.
ITS uplift loads are valid for all lumber species and need not be reduced for duration of load.
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.
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.
SCL (structural composite lumber) is LVL, LSL, and Parallam® PSL.
Web stiffeners required for the ITS Alternate Installation when installing optional joist nails for additional uplift load.
Code Values are based on DF/SP header species.
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.
For 2 1/2" and 2 7/16" wide joists, see top flange hanger tables for allowable loads.

Parallam® is a registered trademark of iLevel by Weyerhaeuser.

This table indicates various allowable loads for ITS/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.

Uplift loads are based on DF/SP members only. See T-NAILERUPLFT for SPF/HF values.

Loads are based on Doug Fir, and have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
Web stiffeners are required on I-joist for additional nailing.
