90 This product is preferable to similar connectors because of a) easier installation, b) higher loads, c) lower installed cost, or a combination of these features. Engineered Wood Structural Composite Lumber Connectors IUS/IUT/MIU I-Joist Hangers The improved IUS is now fully compatible with shallow flange I-joists! I-joists with flange thicknesses between 1 and 1 achieve the full allowable table loads including uplift values and joist nails are not required! The IUS is a hybrid hanger that incorporates the advantages of the face mount and top mount hanger. Installation is fast with the Strong-Grip and Snap-In joist features along with easy-to-reach face nail locations and self-jigging locator tabs. The MIU series hangers are designed for commercial and high load I-joist applications without requiring web stiffeners. The MIU features Positive Angle Nailing (PAN), which minimizes splitting of the flanges while permitting time-saving nailing from a better angle. The IUT features a bend-tab which nails into the I-joists bottom flange when web stiffeners are not used, or directly into the web stiffener. I-joist flange thickness for bend-tab application is 1 to 1 ". This constrains the member, helping to reduce squeaks resulting from joist movement. MATERIAL: See table page 92-96. FINISH: Galvanized UPLIFT LOADS: Models have optional triangle joist nail holes for additional uplift. Properly attached web stiffeners are required. IUT add two additional 10dx1 joist nails for a total uplift load of 480 lbs and 575 lbs (33% and 60% increase respectively). MIU add four additional 10dx1 joist nails for a total uplift load of 720 lbs and 865 lbs (33% and 60% increase respectively). IUS for additional uplift capacity options refer to technical bulletin T-OPTUPLIFTCWP. SIM PS O N Strong Tie MIU with correct PAN installation Typical IUT Installation MIU IUS (some IUS models have triangle holes in header flanges for Min/Max nailing) U.S. Patent 6,523,321 IUT U.S. Patent 5,555,694 Bend tab into the bottom flange and fasten with 10d x 1 nails at approximately 45 . STEP 3 Firmly push or snap I-joist fully into the seat of the IUS. STEP 2 Slide the I-joist downward into the IUS until it rests above the large teardrop. STEP 1 Attach the IUS to the header Starburst detail allows secure seating of joist. SNAP-IN TEARDROP No nails required! Locator Tab Strong-Grips holds bottom chord in position. INSTALLATION: Use all specified fasteners. Verify that the header can take the required fasteners specified in the table. See pages 88-89 for more installation information. IUS fasten hanger to header. Position I-joist into hanger and snap into place. No joist nailing required. Some IUS models have triangle and round header nail holes. To achieve Max. download, fill both round and triangle holes. IUS Locator tabs are not structural. They may be bent back to adjust for hanger placement. IUS for rimboard applications see T-RIMBDHGR. IUT optional seat diamond hole allows alternate attachment of hanger. See T-OPTUPLIFTCWP. Web stiffeners are not required with I-joists when the joist top flange is laterally supported by the sides of the hanger. I-joist manufacturers may require web stiffeners. OPTIONS: These hangers 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. IUS INSTALLATION SEQUENCE
