Simpson Strong-Tie Face Fix Concealed Flange Hanger IUC142/47 47x142mm

Discreet and Strong Support for I-Joists & Solid Timber

The Simpson Strong-Tie IUC142/47 is a non-welded, face-mounted concealed flange hanger, designed to deliver robust support with a clean, unobtrusive finish. Ideal for use with both I-joists and solid timber, it ensures a secure connection while maintaining a minimal visible footprint—perfect for aesthetic and structural timber framing applications.

With lateral restraint provided to the I-joist’s top flange via the hanger’s side walls, this bracket reduces or eliminates the need for web stiffeners (subject to manufacturer guidelines), saving time and materials on site.
