The QEP Pro Installation Pliers are designed to accommodate both the Original LASH and Xtreme Pro Series tile leveling systems. These pliers make pushing the wedges (part B of the Leveling System) into the clips (part A of the Leveling System) much easier than doing it by hand, allowing you to apply the right amount of pressure without overtightening. These tile leveling pliers are ideal to install tile with consistent and professional results.
