BTALU
Concealed Beam Hanger
The BTALU concealed hanger is one solution to connecting timber members together without seeing the connector.
It is designed to be fixed to the header timber and then fully inserted into a slot in the in-coming beam, and held in place with dowels. Holes are drilled through the timber and fin of the BTALU, allowing accurate alignment. This method provides an aesthectically pleasing connection for feature beams.
Note: Fasteners & dowels supplied; dowel length must be specified upon ordering
Holes for the joist have to be site drilled in accordance to positions shown in diagram below.
