Installation

Fixing

On supporting wood member: TU/TUB/TUBS

CNA annular ring-shank nails dia. 4.0 x 50 mm or CSA screws dia. 5.0 x 40 mm.
Lag screws and bolts dia. 10 mm only for TUB/TUBS.

On supported member: Steel dowel S235JR type STD12

TU12: dia. 8 mm type STD 8.
TU16 to 28: dia. 12 mm type STD 12.
TUB/TUBS: dia. 12 mm type STD 12.

The length of the dowels is less than or equal to the width of the supported joist.

TU: wood/wood fastening only with nails/screws.
TUB: wood/wood fastening only with nails/screws or lag screws.
TUBS: wood/wood fastening only with nails/screws or lag screws.

Concrete and steel substrate:

It is not recommended to use hangers on concrete or steel substrate as the size of the bolts makes the distance from the edge of the wood to the dowels non-compliant with Eurocode 5.

Installation

Make a vertical notch in the joist end (width 6mm for TU12 and 9mm for TU16 to TU28),
Mark the position of the dowels on the joist before drilling holes - diameter of the hole according to the diameter of the dowel
Insert the top dowel in the joist
Route a 6mm deep pocket in either the joist end or the header. This is not compulsory, it is used to improve the aesthetic of the connection
Fix Install the joist onto the concealed beam hanger by hooking the joist onto the concealed beam hanger. Top dowel hooks into slotted top hole on the concealed beam hanger.
Install reamining dowels.the concealed beam hanger to the header with nails or screws
