This heavy-duty timber-to-timber multi-truss hanger is ideal for supporting heavy loads when installing joists. It is designed for use in heavy-duty applications such as multiple truss units, main trimmer joists, purlin-to-beam connections, or similar situations where unusually heavy loads occur. Manufactured from 1.5mm thick galvanised steel in accordance with the BS EN 10346:2009 standard for strength, corrosion resistance, and durability. The hanger comes with 36 pre-punched fixing holes, which can be used with 30 x 3.75 mm sheradised square twisted nails, along with bolts where required. The nail holes are 4 mm in diameter, while the bolt holes suit an M12 fixing. The bearing surface on all multi-truss hangers is 75mm.
