Simpson Strongtie JHM125/47 Joist Hanger Masonry 125mm x 47mm x 10

Compact Masonry Hanger for Timber Joists & Rafters

The Simpson Strong-Tie JHM125/47 is a one-piece, non-welded masonry joist hanger designed to provide secure support for timber joists, beams, and trussed rafters fixed to masonry walls. Manufactured from pre-galvanised mild steel, it offers a reliable and corrosion-resistant solution for smaller joist applications in both new builds and refurbishments.

Its compact 125mm height and 47mm width make it ideal for standard joist sizes in floors, ceilings, and low-span roof structures. Sold individually, it's suitable for repair work, testing, or small-scale construction.
