In this case, the installation is made with one ETC434G on the left of the central rafter (hip) and one ETC434D on the right of the central rafter.

Installation

Fasteners on supported member

CNA annular ring-shank nails dia. 4.0 x 35 mm.

Fasteners on supporting member

Wood element: CNA annular ring-shank nails dia. 4.0 x 35 mm.
Steel element: bolts dia. 12 mm (bolt diameter cannot be more than 2 mm smaller than the drill hole diameter).
Concrete element: WA M12-104/5 mechanical anchor or chemical anchor (AT-HP resin + LMAS M12 x 150 threaded rod).

Installation

Use all the specified fasteners for a given installation. Elements made with 2 plies must be assembled with each other so that they act as a single element (see Eurocode 5).
