The wedi Board Connectors are plastic stabilising connectors for the initial connection of wedi building board systems. Available in 3 variants – 90°, 180° and a Wall Connector.
The 90° Connector is for fixing two boards together in a right-angled corner configuration. The 180° Connector is used when abutting two freestanding boards vertically. The Wall Connector is fastened to a suitable wall then used to support the edge of a board that is then butted up against the wall in a horizontal configuration.
You can see examples of them being used in the datasheet linked below.
