The Clip System is a kit composed of a cove-shaped profile Coflex CR base module and Kerajolly KJ flanges, which must be ordered separately. The flanges are ordered based on the thickness of the tile. The thickness of the Kerajolly KJ profile should be 2 mm thinner than the tile thickness, given that when the KJ is inserted into the track of the Coflex CR it takes up 2 mm. Example: the tile on the wall covering is 8mm thick and that on the floor covering is 10mm: Each CR module will contain a 6mm KJ for the wall and an 8mm KJ for the floor.
