98 Engineered Wood Structural Composite Lumber Connectors TOP FLANGE HANGERS ITT/MIT/HIT/ITTM Engineered Wood Products Hangers A dedicated range of Top Flange I-joist hangers meeting the unique needs of I-joists while offering superior performance and ease of installation. ITT Bend Tab Nailing Nail the ITTs special bend-tab with 10dx1 nails at approximately 45 into the bottom flange of the I-joist when web stiffeners are not used. The bend tab can also be nailed directly into the web stiffener. This constrains the I-joist, helping to reduce squeaks resulting from joist movement. Reduced embossing on the ITTs top flange, and the hanger height sized less than the joist height allow easier fitting for smooth floor alignment. I-joist flange thickness for bend-tab application is 1 to 1 ". MIT/HIT Patented Positive Angle Nailing This feature is specifically designed for wood web I-joists when used with the MIT or HIT. With Positive Angle Nailing (PAN), the slotted hole material is not removed, but is used to channel and confine the path of the nail to the optimum angle. PAN minimizes splitting of the flanges while permitting time-saving nailing from a better angle. ITTM masonry-to-wood connectors can be directly embedded into a grouted block wall. It can also be installed on top of a masonry or concrete wall using Titen screws. See Top Flange tables on pages 104 to 113. MATERIAL: ITT 18 gauge; MIT, HIT 16 gauge, ITTM 12 gauge top flange and 18 gauge stirrup FINISH: Galvanized INSTALLATION: Use all specified fasteners. Verify that the header can take the required fasteners specified in the table. ITTs face flange triangle hole may be used with triangle holes in the joist for additional uplift (optional); optional diamond hole in seat allows attachment of hanger to I-joist. See T-OPTUPLIFTWP. ITTs bend-tab may be nailed unbent into plywood web stiffeners. ITTM installed into grouted block wall: embed into block with a minimum of one course of grouted block above and one course below the top flange. No Titens required. ITTM installed on concrete masonry wall: install "x1 Titen screws through preformed holes on the hanger. ALLOWABLE LOADS: The ITT, 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 . For sloped joists up to :12 there is no reduction, between :12 and up to :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. CODES: See page 12 for Code Listing Key Chart. 2 MIN.
