This innovative concealed beam connector with high load-bearing capacity and low installation depth is ideal for concealed wood/wood connections (visible areas) of secondary beams to main beams or posts

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

Proof of Performance

ETA-09/0301

Notice

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.

Application area

Instructions

Select a template insert

Attach template: The fixing holes are used to attach the template to the beam.

Set the trimming depth of 14 mm

Mill the recess

The upper thrust ring enables a simple and fast milling process without damaging the template.

Mark center of secondary beam.

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. The connector must be mounted flush with the upper edge

Then screw in the remaining screws at a 35° angle.

Fit the connector
into the prepared recess
in the main beam and
screw in the screws.

Hook the secondary beam into main beam from above

Simple mounting thanks tocentering aid.
