GIGANT 150 x 40 Heavy Timber Beam Hanger

The GIGANT 150 x 40 is a heavy-duty concealed beam hanger designed for high-capacity structural connections in timber framing, log building, and mass timber applications. The connector is composed of two identical steel brackets that interlock in a dovetail-like motion, allowing the secondary beam to slide into position with immediate load transfer.

One bracket sits in a recessed housing and the other mounts directly on the beam surface using KNAPP SK screws. The short hooking path supports fast assembly, while the self-tensioning geometry maintains long-term joint compression. The connection can be installed fully concealed or visible depending on the design requirement.
