This click and connect is a connector piece to join two Artiteq Click Rails together, as well as being an attachment-clip for the Artiteq Click Rail. This clip is also available in a 3-ring option for extra grip on uneven walls. Besides being an attachment clip it can also be used as a drilling template. Position the click and connect along the wal and against the ceiling and you have the perfect distance from the ceiling to drill the plughole. Use one for every 40 cm of rail.
