Wall Adapter Plate TWA


The wall adapter plate serves as a base plate for the connection of a steel beam of the Simotec beam systems 100 and 120 to a concrete wall.

Scope of delivery

The connection parts set TWAV (Part number 803572) must be ordered separately and consists of the following components in a polybag:
4 x Beam Clip SPA 5P AU M12 HCP
4 x Countersunk Screw SK M12 x 70 ISO 10642 10.9 HCP
4 x Hexagon Nut NT M12 DIN 934 GLT HCP
4 x Washer US 12/125 140 HV HCP


The four countersunk screws of the connecting parts set are inserted into the countersunk holes.The panel is then attached to the steel beam by beam clips, washer and nuts (included in the connecting parts set) to the steel beam. The wall adapter plate is then fixed to the concrete wall with four anchors. The anchors must be ordered separately and selected depending on the substrate.
