IUB

Metal Web Joist Hanger

The IUB/HIUB hangers support metal web joists and solid timber joists without the need for plywood gussets. They incorporate the unique feature of bottom flanges, which provide enhanced capacity.
 

  • Can be used on metal web joists or solid joist headers.
  • Eliminates the need for plywood gussets when supported from a metal web joist.
  • IUB Bottom flanges provide enhanced download capacity and quickly sets the hanger onto the header.
  • Obround holes in face to provide easier nailing access in tight locations. 
  • IUB: Positive Angle Nailing (PAN) of joist to speed installation and reduce the likelihood of splitting.
  • IUB has hexagonal holes for SSH screw installation and optional triangular nail holes for additional download, when used in conjunction with a plywood gusset, and additional uplift capacities.

Installation

  • Position the hanger onto the face of supporting floor joist, ensuring the bottom flanges are tight up against the underside of the bottom chord.

  • Install 3.75 x 30mm nails into the holes within the hanger bottom
    flanges. Fill all face round and obround holes with 3.75 x 30mm square twist nails.

  • Sit the carried joist into the hanger and install 3.75 x 30mm  nails through the angled pan nail holes into the joist.

  • For enhanced uplift, fill all joist triangular nail holes with 3.75 x 30mm nails.

  • For SSH screw installation the IUB may be installed with 4-SSH6.0x60 screws through the hexagonal holes in the face.
