The RLS 3mm Kit provides all the tools you need to use the Raimondi Levelling System on tiles up to 12mm thick. It consists of 1 pair of special traction-adjustable pliers for floor covering allowing quick and easy insertion of the wedge into the clip and optimising pressure on the tile. 100 wedges and 100 3.0mm clips are provided for use with tiles of thickness 3-12mm. RLS is also the quickest and easiest to remove: spacers can be kicked gently to remove them from floor, without the need for a special tool. The video shows the sister product 180KIT100.
