Product Dimensions
Product characteristic capacities - Timber beam to timber beam - full nailing - with slope and skew α=30°
R2,k capacities can be calculated as R2,k = R1,k x (nb of dowels - 1) / (nb of dowels).
The top dowel is not considered for the uplift capacities as it is placed in an open hole.
Product characteristic capacities - Timber beam to timber beam - full nailing - with slope and skew α=45°
R2,k capacities can be calculated as R2,k = R1,k x (nb of dowels - 1) / (nb of dowels).
The top dowel is not considered for the uplift capacities as it is placed in an open hole.

Installation
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
