For supporting timber joists and structural composite timber from masonry walls. A non-welded construction to BS6178. Increased safe working loads, higher side flange and resists rotation. All hangers 150mm deep and above are undersized by 10mm to allow for notching of ceiling joists for flush finish of plasterboard. The back plate of the hanger should be flat against the supporting masonry. Before any loads are applied there should be at least 600mm of cured brick/block work above the hanger. The end of the joist should then be flush against the back of the hanger and side web holes filled with 30mm x 3.75 square twist nails.
