99 Engineered Wood Structural Composite Lumber Connectors TOP FLANGE HANGERS ITT/MIT/HIT/ITTM Engineered Wood Products Hangers OPTIONAL NAILING FOR INCREASED UPLIFT NAILER TABLE This table indicates the maximum allowable loads for ITT/MIT/HIT hangers used on wood nailers. The header nail type must be substituted for those listed in other tables. 1. Loads are based on Doug Fir, and have been increased 33% and 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. 1. These hangers may deflect an additional at design load.

Uplift loads are based on Douglas Fir, and have been increased 33% and 60% for earthquake or wind loading with no further increase allowed. Divide by 1.33 and 1.60 for normal loading criteria like cantilever construction. For SPF use 0.86 x DF/SP uplift load. 2. Titen masonry screws are x1 . 3. 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 column. 4. 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 to 1 , use 0.85 of the I-joist header load. For flanges with thicknesses from1 to 1 , use 0.75 of the I-joist header load. 5. Minimum solid header thickness to achieve ITT table loads is 1 ". 6. SCL, structural composite lumber, is laminated veneer lumber, Parallam PSL and TimberStrand LSL. 7. Code Values are based on DF/SP header species. 8. ITTM loads are based on 2000 psi minimum concrete or grout. 9. I-joists with flanges less than 1 thick used in combination with hangers thinner than 14 gauge may deflect an additional inch beyond the standard limit. 10. Mid-wall installation requires minimum of one grouted course above and below the hanger. 11. ITTM411.88, ITTM414, and ITTM416 models are available. Parallam and TimberStrand are registered trademarks of Trus Joist, a Weyerhaeuser company. NAILS: 16d 0.162" dia. x 3 long, 16dx2 0.162" dia. x 2 long, 10d 0.148" dia. x 3" long, 10dx1 0.148" dia. x 1 long. See page 16-17 for other nail sizes and information. IT SERIES WITH VARIOUS HEADER APPLICATIONS POSITIVE ANGLE NAILING Correct Nailing Approx. 45 o angle Nail at wrong angle Do not bend tab Nail too long Use a 10dx1 nail (Simpson N10 HDG shown) Bend the tab with a hammer. Hammer the nail in at approximately 45 . The tab is now correctly installed. IUT ITT INSTALLATION (VPA SIMILAR) Some model configurations may differ from those shown on page 98.
