- Sloping connections can be constructed at angles of 15° to 165° and gradients of 0° to 55°. Screw into grain-cut timber at an angle of 35° using ASSY 5 x 80 mm countersunk-head, full-thread screws. The screw-in angle is determined by the sheet metal guide.
- High load-bearing capacity coupled with low installation depth (14 mm)
- Conical, swallow tail-style geometry for self-centring and gap-free contact pressure
- High level of possible pre-fabrication in the workshop and easy and quick on-site installation
- Sheet metal hot-dip zinc-plated on both sides (S250GD + Z275 [approx. 20 µm]), thickness 3.0 mm in line with EN 10346:2009
- Application in utilisation class 1 and 2 in line with EN 1995:2013

It is advisable to use the corresponding milling template set for easy and quick pre-assembly.
Screw into grain-cut timber at an angle of 35°. The screw angle is determined by the shape of the tabs.
The main beam's transverse strength must be verified separately. If necessary, the joint should be made using ASSY plus VG full-thread screws. For loads perpendicular to the secondary beam axis, the transverse strength must also be verified for the secondary beam. If the main beam is subject to torsion, it must be secured against twisting.

Load-bearing connections of timber joists to timber main beams or posts in visible areas
Approved fasteners:
ASSY 3.0 countersunk head screw with full thread 5 x 80 to 120 mm (lg ≥ 72 mm) in line with ETA 11/0190 mm
Installation guide:
- Select the template insert
- Place the swallow tail-shaped part of the connector centrally on the previously marked secondary beam and screw in the centring screw first of all. Mount the connector flush with the upper edge
- Screw in the remaining ASSY screws at an angle of 35°
- Fit the connector in the prepared recess of the main beam and screw in the screws
- Fit the secondary beam into main beam from above
