Specification

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 the end grain at an angle of 35° using ASSY 5 x 80 mm countersunk head screw with full thread

The screw-in angle is determined by the sheet metal guide

High load 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 batch hot-dip galvanised on both sides (S250GD + Z275 (approx. 20 µm)), thickness 3.0 mm, in accordance with EN 10346:2009

Application in utilisation class 1 and 2 in accordance 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-in angle is determined by the shape of the tabs.

The transverse tension of the main beam must be verified separately. If necessary, the tension should be made using ASSY plus VG full-thread screws. For loads perpendicular to the secondary beam axis, the transverse tension 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.

Instructions

Approved fasteners:

ASSY 4.0 countersunk head screw with full thread 5 x 80 to 120 mm (lg ≥ 72 mm) in line with ETA 11/0190 mm

Installation instructions:

Select a 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. The connector must be mounted 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
