IUS/MIU I-Joist Hangers

Material

• IUS — 18 gauge; MIU — 16 gauge

Finish

• Galvanized

Installation

• Use all specified fasteners. Verify that the header can take the required fasteners specified in the table. See General Connector Installation for more 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 technical bulletin Hangers on Rimboard Headers (T-RIMBDHGR).
• IUS — I-joists with web stiffeners or rectangular sections can be used with the installation of (2) 0.148" x 1 1/2" nails into the optional triangle joist nails.
• IUS — web stiffeners are not required with I-joists when the top flange is laterally supported by the sides of the hanger unless required by the I-joist manufacturer.

Uplift Loads

• Models have optional triangle joist nail holes for additional uplift. Properly attached web stiffeners are required.
• MIU — add four additional 0.148" x 1 1/2" joist nails for a total uplift load of 975 lb.
• IUS — add web stiffeners and two 0.148" x 1 1/2" joist nails in the triangle holes for a total uplift of 365 lb.

Options

These hangers cannot be modified. However, these models will normally accommodate a skew of up to 5°. 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.
