Heavy-Duty, Extended Joist Hanger for Loft and Structural Timber Applications

The Simpson Strong-Tie JHA450/47 is a robust, long leg joist hanger designed for secure timber-to-timber connections. Constructed from 1.5mm pre-galvanised mild steel, it offers strong support for structural joists—especially where extended drop and below-support installations are required, such as in loft conversions or floor extensions.
