It all starts with the desired louver type. The louver type defines the clip. The clip connects a louver to the rack arm. The standard S-system clip is used for most louver types. Some types however require a custom slat clip, because of the size (width) or shape of the louver.
The clip is a two part mechanism. Jointly, the pivot arm and slat clip determine the position of the louver; from open to close, and any position in between.
The aluminium louvers up to and including the 117-E, and the wooden louvers up to and including the 94-W make use of the S-system and the standard S-system clip.
The exceptions are the aluminium 48-E, 50-A, and the 80-R. As well as the wooden 50-W. The clips for these louver types are described separately, and listed in the menu in the sidebar.
The pivot arm is pressed into the top track of the rack. This makes a clipping sound, and the reason this part of the assembling process is called clipping.
The slat clip is the part that holds the louver. The slat clip is connected to the pivot arm. Together these parts operate like a knee or elbow joint.
The pivot arms and slat clips are available in four colours:
